Such an enjoyable read! This is my first book by this author, so I have not read the previous books of this series, but after reading this one, I realized I have been missing out and I would love to go back and read them all! Plus I think the whole murder mystery will make much more sense if I start from the beginning. That being said, I was still able to enjoy this story. It pulled me in right away and I was captivated till the end. Ms. Jeffries does an excellent job of bringing the story and the characters to life. The characters were well-developed and worked well together. The storyline flowed smoothly and the plot twists kept me turning the pages, anxious to see what happens next. The romance is a well-written enemies to lovers story and the interactions between Sheridan and Vanessa were entertaining and witty. I had so much fun reading this, I did not want to put it down! Ms. Jeffries is definitely going on my must read authors list! I can't wait to read more of her books!

Oh I really really like this story!
Along with his stepsiblings, Sheridan Wolfe, Duke of Armitage, is determined to finally solve the mysteries behind the suspicious deaths of their mother’s three husbands. Tasked with investigating a possible suspect, Sheridan finds himself near her captivating daughter, Vanessa Pryde, who seems utterly smitten with a roguish London playwright.
But it’s Sheridan who Vanessa truly has her sights, and her heart, set on. Her theatrical flirtation is intended only to break through his business-like demeanor and guarded emotions. And as Sheridan’s jealousy becomes aroused, the two soon find themselves propelled into a scheme of an altogether different kind, involving a pretend engagement, a secret inquiry—and a perhaps not-so-secret leap into true love . . .
This two are just adorable. Sheridan lost his “one true love” when he was young and now he’s fighting his attraction to Vanessa because he doesn´t want to suffer again. Vanessa is strong and sassy, and I loved them together. The dialogs are witty and emotional and there are hot kisses and many sexy times. And there´s a bit of mystery too!
It´s a beautiful and enjoyable reading and I highly recommended it!
I received an advance review copy for free, and I am leaving this review voluntarily.

Sheridan Wolfe, Duke of Armitage, is determined to once and for all find out who was behind the suspicious deaths of his uncle and father - along with his mother's other two previous husbands. With the help of his siblings, and their significant others, they know that events in the past play a key part in figuring out who is behind the murders. They each have their own person to question. Sheridan is tasked with questioning Lady Eustace, and the best way to do that is to get close to her daughter Vanessa. With Vanessa's affections caught up with a local poet, Sheridan feels like they can both benefit from a fake courtship: Sheridan will have ample opportunity to question Vanessa's mother, and Vanessa can make her unrequited love jealous enough to actually commit to her.

But Vanessa has a secret. She's not really in love with the poet. She's actually quite taken with Sheridan himself, but he's never seemed to notice her before. Vanessa hopes that being in constant close proximity with one another will force Sheridan to finally see her. But will they ever be able to reach one another with all the secrets floating around?

I've rather enjoyed this series. The big draw for me was following the murder mystery throughout each book. I liked how it linked each story together. If I'm being honest, I wish that it was more prevalent. I know that this series is romance first and the mystery is something extra, but I wish that we could have seen more cohesion in regards to putting the pieces together at the end. I think this is especially highlighted because we're at the end and readers are figuring on things getting solved. There was just still so much for the siblings to piece together that I would have appreciated some scenes from other characters' points of view as they question their respective suspects. Since each book focuses on a different sibling though, I understand why Sheridan / Vanessa were the focus. Sabrina Jeffries would have had to setup the flow of the story differently from the onset for it to have made sense at the end.

I won't say that the reveal was super shocking, but I always enjoy how the past ultimately influences the present / future and oftentimes revisiting the past will give us the insight we're looking for.

As it stands, Vanessa and Sheridan's road to happiness was a tangled web indeed. There were quite a few times I had to stop and remind myself why they were pretending to be together. Who it was supposed to benefit and what secrets were still being kept. I think, for the most part, Sabrina Jeffries handles the various points of their fake relationship rather well. I mean that if you take both Vanessa and Sheridan's parts and view them separately it makes a certain sense. It's also speaks a lot to things that we leave unsaid. To see the points where Sheridan and Vanessa's feelings for one another actually converge yet they've set their own roadblocks in between what they could have together, it's almost a bit comical dare I say. But I like them together and I like how well they kind of play off of one another.

The highlight for me is the family interaction. I think with this being the last book we get a good view of all the siblings and their significant others together quite a few times and I love seeing that connection especially given the fact that they are such a large blended family.

Overall, I've found this series to be enjoyable. I'd say you could definitely read these as standalones but you might miss the build up of the mystery that runs throughout.

Undercover Duke is the fourth and last book in the Duke Dynasty series. I have only read the last two but there really is no problem jumping in with this one.

The family of the dowager duchess have come to the conclusion that her three husbands (all dukes, although one wasn't when she married him) were murdered. They have narrowed down the suspects to three women who were guests at both events where the first two husbands were murdered. Our hero Sheridan's eldest brother Greycourt, was to question his aunt Cora, one of the suspects, but in his anxiety over his wife's impending delivery of their baby, asked Sheridan to do it instead. Sheridan reluctantly agrees. He is a bit concerned about dealing with Grey's cousin Vanessa,. who he is attracted to against his will. Vanessa is attracted to Sheridan but in trying to divert attention from that attraction she told her cousin she had a tendre for a poet and then when questioned by Sheridan she named Konrad Juncker, a friend of Sheridan and Grey's half brother. Sheridan agrees to help her get Juncker by appearing to court her to make Juncker jealous. His real reason is to get a chance to question Vanessa's mother.

I enjoyed the family dynamic and there were some funny scenes between the siblings and between Juncker and Sheridan. Sheridan is lusting after Vanessa from the beginning and won't admit to being in love with her so the romance is a bit flat to me. The mystery of the murderer is resolved at the end with a bit of drama.

I received an ARC from the publisher however the opinion expressed is my own.

"Undercover Duke" by Sabrina Jeffries
Loved this story!!
I did not skip a page nor a paragraph nor a single word in this Regency Romance-Mystery adventure. I had a difficult time putting the book down for any reason, including that my eyes were so tired it was difficult to keep them open and focused. This is a good romance story with an intriguing set of questions. Who is/was behind the deaths of 3 dukes, and Why. Will you figure out the Who? And the Why? Happy Reading ! !
Note: I received an ARC of this story from the publisher. This review is my honest opinion.

Undercover Duke by Sabrina Jeffries is the fourth and final book in the series Duke Dynasty. I have enjoyed the series to date and was looking forward to Sheridan’s story. There was also that pesky mystery of who was killing the Dowager Duchess’s husbands. I like how the siblings were working together to solve the mystery. I also appreciated being totally clueless to the guilty party until this novel. (However, I did figure it out early on in this novel.)

Sheridan Wolfe, Duke of Armitage is determined to help his siblings solve the murders. He is also determined to save his land and tenants despite the lack of funds available. Vanessa Pryde’s mother is a complete and utter pill. She and her husband helped raise Grey (with a great deal of abuse and attempted theft of his heritage.) Sheridan is determined to use Vanessa to help him get close to her mother. She is determined to get him to pay attention to her even if it requires subtrafage.

I didn’t love the story between Sheridan and Vanessa until part way through the book and by then I had a strong suspicion who the guilty party was. Having said that I enjoyed reading the novel and am sorry there are no more siblings to marry in this family. Undercover Duke by Sabrina Jeffries is a good wrap up of the series.

This one was my least favorite in the series. I think it’s just because I never fell in love with Vanessa or Sheridan. The story was good but didn’t live up to the previous three books.

Sheridan and Vanessa are such a good couple! I love a historical romance with some mystery, especially when on of them is determined to find the truth. It always makes for a compelling story. Ms. Jeffries is such a good author when it comes to sexual tension, and both main characters have tons of it! Overall, the story and characters are so interesting in this novel. I loved reading this book, and it's so easy to read in one sitting when you love it so much!

Undercover Duke (Duke Dynasty, #4) by Sabrina Jeffries
This is a wonderful series full of mystery and a fantastic family of step siblings and their spouses. This story is Sheridan Wolfe, Duke of Armitage and Vanessa Pryde's story. There is a murder mystery to solve, angst, laughter, tears, love, distrust. plenty of twists and turns and steam to get us to their HEA.
Reasons I enjoyed this book:
Happily Ever After Unpredictable Scary Romantic Twisted Tragic Easy-to-read Steamy Entertaining Funny Great world building Action-packed Wonderful characters Page-turner Tear-jerker

"Undercover Duke" was a great conclusion to the series about The Dowager Duchess of Armitage and her four sons and one daughter. It was great to learn more about Vanessa Pryde who we met in book one. Getting to know about more about the last duke - Sheridan, Duke of Armitage was lovely as well. Vanessa and Saintly Sheridan have great banter and laughter which always makes a book great to read. It was a fast paced story with some subterfuge and lies by omission. I'm glad the characters took the mature way of clearing up mistakes that were childishly created. The slow build to a long love was heartwarming. I'm glad the mystery of the deaths was finally solved. I would definitely recommend this book to my friends. It was also nice to catch up with all the previous couples.




Small spoiler alert.....one sister-in-law was "due any day" in Chapter Sixteen, but then she is due "some time next year" in the epilogue -- an editor might want to catch that.

First off Fake Romance Tropes are divine. I get so sucked in by the whole are we dating? Aren’t we dating? And then BAM suddenly he’s acting like a real suitor who can’t abide his lady’s honour being compromised by the other man who he thinks she actually wants.

It was flawless. I couldn’t get enough of them both I had to just keep reading.

The murders/ plot of intrigue was secondary for me, so I wasn’t too upset that it didn’t take on a more dominant role in the book. I was very happy to put all of my energy into the relationship between our hero and heroine.

My one criticism would be that when they found themselves in a marriage that was kind of but not really a marriage to start it was like they had flipped a switch and were acting so affectionately.

Maybe it’s just the masochist in me but I would have rathered the angst of being in a marriage with someone they loved but didn’t think could love them back to be stretched out a bit more just to really make them sweat and cause more suspense on the face of betrayals about keeping information from each other.

Over all- I adored it.

It had a reserved duke, a smart and wilful female protagonist, and fake relationships turned to true love.

What’s not to like?

I received this book for free from Netgalley. That did not influence this review.

I enjoyed book three in the Duke Dynasty series by Sabrina Jeffries, Who Wants to Marry a Duke, despite not having read the first two books. The series includes a murder mystery (at least three murders) that remained unsolved, but hinted at, at the end of book three. It left me intrigued enough to want to learn whodunnit.

Book Four, Undercover Duke, solves the mystery satisfactorily, but the romance fell flat.

The basis for the series is that Lydia Fletcher married three dukes in succession, all of whom died under mysterious circumstances. Her sons, by different fathers, have teamed up to solve the case. Previous novels have matched up two of the sons with feisty brides. The remaining son, Sheridan Wolfe, Duke of Armitage, has no wish to marry. When he was young, he had fallen in love with a woman who died of consumption before they could wed. He never wants to feel that pain again.

However, he is drawn to Vanessa Pryde, a distant cousin, who he first met about a year and a half earlier. She has an awful mother who is trying to marry her off. But Vanessa has carried a torch for Sheridan ever since they first met and is uninterested in anyone her mother pushes at her.

The hero and heroine refuse to admit that they are interested in one another. Vanessa pretends to be chasing after a playwright (who happens to be a close friend of her cousin, one of Sheridan’s step-brothers.) She is hoping to make Sheridan see that she is no longer a child and to make him jealous.

For his part, Sheridan is jealous. But he gets assigned the task of investigating Vanessa’s awful mother, who is one of the suspects in the murder investigation. So he pretends to court Vanessa to get close to her mother, while pretending to Vanessa that he is helping her make the playwright jealous. (This is NOT the most convoluted part of the plot; that would be the relationships between the brothers. I hadn’t found it hard to follow book three without having read the others, but this one suffers from the lack of detailed backstory. It would probably be best to read the whole series in order.)

Vanessa is a pleasant, intelligent heroine, who is far too forgiving of Sheridan’s lies and far too guilty about her own rather minor deception. Much of the book is overwrought worrying that could be readily dispelled by a simple conversation. Instead, she tries to win him over with sex.

Sheridan refuses to fall in love, but has no qualms about lusting after Vanessa. The novel relies too much on sex to drive the relationship and fill pages. His primary emotions seem to be jealousy and uncontrollable desire. He just isn’t likeable as a protagonist.

There is some entertaining banter, but also some clunky conversation. And the dialogues during sex were awkwardly corny/strained.

Overall, I think this book would have been more enjoyable had I been more invested in the series. I shouldn’t have started mid-series.

Undercover Duke is a gorgeous read in every way. Fun, feisty and passionate, this story keeps you entertained. Sheridan is swoon worthy and loyal and Vanessa quickly melts his heart towards her. What starts as a game of mystery and schemes soon turns into a game of true love. A wonderful happily ever after.

Mutual pining between the last duke on the list Sheridan and Vanessa, his half brother Grey's cousin.
This convoluted family might give you a headache trying to keep them straight, thankfully the books all have a lineage at the front to help with that.
Sheridan offers to help Vanessa make another man(that she doesn't care about at all)jealous, she's just trying to make Sheridan notice her.
Sheridan thinks she's a flighty, expensive girl that he could never afford to marry so he tries to treat her like a little girl/sister to avoid his feelings about her. Vanessa tells Grey one tiny fib about being in love with a poet to avoid telling him she has feelings for his brother and it gets blown all out of proportion over the course of the series until we get to this book and it all comes together in a bit of a convoluted and funny way.
The mystery murder plot is also wrapped up in this book, so I do recommend you read this series in order so you know what's going on.

This is my fair and honest review, voluntarily given and in my own words, for this ARC. Such a clever series! Family intertwining and growing and yet with such unique plots and twists! All have been well written and definitely should be on your TBR list!

I enjoyed reading this book, but the pacing was a bit choppy, with parts of it more interesting than others. The romance was pleasant but fairly standard. It was nice to get closure to the mystery, but it wasn't hard to pick out who the villain was from early on in this installment.

The mystery continues and the wonderful characters are all back trying to solve who killed their fathers and uncle. Sheridan has been tasked to find out if Lady Eustace is behind his stepbrothers and his own father’s death. Which meant he needed to get close to her daughter Vanessa in order to get close to her for questioning. Not a easy task when Lady Eustace hates his family and her daughter is in love with another man. Or so he believes! Vanessa has her sights set on Sheridan.
Many more twists and turns to the final conclusion of who done it. Must really read in order or you will be missing many pieces of the puzzle. Very entertaining series.
I am voluntarily posting an honest review after reading an Advance Reader Copy of this story.

Once upon a time, there was a beautiful, bright, kind, vivacious diamond of the first water who married a duke during her first season. After his untimely death, she married two more dukes and had a total of five children before the age of five and twenty. Luckily for all of them, the last duke managed to live long enough to raise and be a father to all five of those children. Upon his untimely death, those now-grown children begin to put two and two together and realized that someone had been killing off their mother’s husbands. Who would hate their mother that much? As we’ve worked through each of her children’s books - Fletcher “Grey” Pryde, 5th Duke of Greycourt and Beatrice Wolfe (Project Duchess), Lord Heywood Wolfe and Cassandra Isles (A Perfect Match – a novella in the Seduction on a Snowy Night anthology), Lady Gwyn Drake and Joshua Wolfe (The Bachelor), and Marlowe Drake, the Duke of Thornstock and Miss Olivia Norley (Who Wants to Marry a Duke) – we’ve gotten more and more hints about who the murderer is. You may have figured out who it is – or not – but not the true reason behind it and you won’t know that until the murderer is revealed.

Since the murders have been solved and all of the step-siblings have found their HEAs, I think this must be the last book in the series. There is a novella coming out near Christmas that will feature a recurrent character, Juncker, in this series, but I don’t really think it is part of the series. Anyway, this book was a delightful, exciting, twist-and-turn, cannot-put-it-down wrap-up for the series. All the threads are wrapped up and we get to visit with all of the step-siblings. It is well-written, delightfully complex, and wonderfully sensual – not to mention breath-holding while in pursuit of the villain.

Sheridan Wolfe, new Duke of Armitage, was the one to put the puzzle together and recognize that all of the deaths in his family may not have been what they appeared to be. With the death of his father a year ago, Sheridan inherited a duchy that was on the brink of insolvency. It seems that no matter what he does, how hard he tries, he cannot bring the estate around to make it pay for itself. He doesn’t blame his father because he was only the duke for a few months. His father was never supposed to be the duke, but when his uncle died unexpectedly, his father had to return to England and assume his role as duke. It was his uncle who bankrupted the duchy. Sheridan – known to his siblings as Saint Sheridan – always tries to do what is right, what is correct and honorable and he just cannot see a way to save the duchy. He certainly won’t consider marriage to an heiress; he just can’t do that. He supposes he’ll have to marry and produce an heir someday, but that will be far in the future if at all. He loved once and it nearly killed him – he won’t do it again.

Vanessa Pryde has been attracted to Sheridan Wolfe since the day she met him. However, if he notices her at all, he treats her as a little sister. She is so frustrated that he won’t notice her as the grown woman she is! What is a girl to do? Well, she’ll just do a little scheming and make him jealous by pretending to be interested in the poet/playwright Juncker – and she’ll ask Sheridan to help her make Juncker jealous. Convoluted – Yes! Misguided – Yes! However, it is fun to watch Sheridan stew because he hasn’t been as unaware of her as she thinks. Of course, he has his own motives for agreeing to help her – and they aren’t exactly aboveboard either.

I definitely recommend this book and this series. It is delightfully entertaining with wonderful, very likable, and relatable characters. The book, the plot, the characters, the romance, was so engaging I couldn’t put it down and read it straight through in one sitting. If you try it, I hope you will enjoy it as much as I did.

I voluntarily read and reviewed an Advanced Reader Copy of this book. All thoughts and opinions are my own.

This was a fun historical romance with a great cast of characters - I really enjoyed Sheridan's family. The murder mystery was also a nice touch and a fun element to have in a romance novel. Would highly recommend this series to anyone interested in the genre.

Thank you Kensington Books for the ARC!

Will them getting closer bring out the culprit...

Before this series, I had only read one book by the author. So with her dukes dynasty she caught me and if not for my crazy reading schedule, I would have jumped on this book weeks ago, as I was eager to know who was behind the family’s dramatic deaths, and while my doubts grew right with the story progressing, I did not saw the whys and hows until it was revealed.
Vanessa is easy to like despite her many schemes, which are rather harmless pleasantries than real threats. She sure wants to sway Sheridan to see her as more than his half-brother childhood friend, but she does not plan to trick him to wed her. She grew up with uncaring and unloving parents, she too was manipulated to do their bidding so she learned from the best, still she only seeks to find what she never got, someone to love and who will love her in return.
Sheridan is the younger of the Duke siblings, and the one left with a near bankrupt title. He is also the more reserved of all his siblings, never expecting to become a Duke, he had an other carrier in mind, far more suitable for his character. Yet now he must find a way to restaure his estate but also follow one of the many leads his family has to uncover the culprit behind the murders darkening his kin’s history.
Thus how he get close to Vanessa as she is the daughter of one the suspects.

Sure their relationship began the wrong way as he offers his help/friendship with first the intend to find the answers he is seeking all the while she embarks him in her own plot with the hope to awaken his interest.
Until they are caught and must face the music of their errors.
An easy to read and entertaining story.

I have been granted an advance copy by the publisher Kensington Books, here is my true and unbiased opinion.
