Frankie Bumgarten takes care of her own so when someone tries to break into her home, she is prepared to fight back.   To her astonishment, it's Reynard Boulton, nephew of the Viscount Tannehill, bringing her drunk Uncle, Red, home.  Immediately, Frankie discovers who he really is.  Frankie has no interest in the man trying to win her hand, but she does want to know more about the man her sister is falling for.  That is how she finds herself enlisting the aid of Reynard.

Reynard cannot deny the attraction between him and Frankie, but he made a promise to his friend, one that he will honor.  He is to keep an eye on the Bumgarten girls and keep them safe from harm.  When Frankie asks for Reynard's help, he is jealous of her interest in another man.  Reynard does his best to keep his distance, but protecting Frankie and keeping her at arm's length proves to be a tiring endeavor.  What can he do when all his defenses are crumbling away to nothing?

We first meet the enchanting and endearing Bumgarten sisters in author Betina Krahn's first installment of the SIN AND SENSABILITY series,  A GOOD DAY TO MARRY A DUKE.   I loved Daisy, the oldest sister, and her duke, Ashton.  The idea of Americans coming to London to make advantageous marriages is captivating enough, but the fact that these young women are anything but your average Society miss only add to the excitement.  They may be ladies, but they know how to do a lot of unladylike things and aren't afraid to go after what they want.  Book two, THE GIRL WITH THE SWEETEST SECRET is Frances, Frankie's, story.  It is clear as glass, from the beginning, that Frankie and Reynard belong together.  They more develop a friendship before they find love, but it only makes their tale all the sweeter.  I will be anxiously awaiting the next Bumgarten sister's story.

I received a free ARC version of the book in exchange for a honest review. All opinions are my own.

I was very excited for this book. It sounded great. However, the book comes accross as slow and (I'm sorry to say) boring.  It's not that there isn't drama. There's a duel, a woman trying to force a man to marry her, a notorious gossip/spy and more. I have no idea why the book is boring but it is.  If I had to say anything it would be the sentence structure; the sentences are often very long and give the book a slow pace as a result.

Out of the two main characters, I love the fox the most. He intense but broody. I wish he more like everyone thought of him (dark, notorious for knowing everyone's secret, selfish). He doesn't really fufill any of his promise. However, I did like how Frankie's uncle said ' he is all those things but not with you). At least that was a paraphrase of that.

This highly entertaining story is the 2nd in the Sin and Sensibility Series and will make you cry, smile and cheer for the lovers. This standalone, HEA historical romance incorporates the love lives of three different couples, the main characters being Frances Bumgarten and Reynard Boulton. 
The story has great flow, fully fleshed out characters, secrets kept, secrets shared, intrigue, an evil villain, and warm romance. This author pulls you into the story and the characters lives, making you feel all of their emotions every step of the way. I can hardly wait until the next story is written and will go back to read the first in this series.
I received a copy of this book through NetGalley for my honest opinion.

At first i thought the book was rather chaotic with at least three romances going at once, but after awhile it got really interesting and the author seamlessly wove the plots of all three together in a sensible, fulfilling story for each. Don't be put off by the background stories as i was at first and actually thought i would not finish for that reason, but i refuse to not finish a book once started and i plodded on. It was well worth it. The stories meshed and each one was fleshed out enough to actually be an actual of tale of love for each. I truly enjoyed the history lesson (author's notes) of the time period especially. I always appreciate when an author takes the time and effort to either explain terminology or actual events. I now want to desperately read the first book in the series and cannot wait for the third. It may just be the most interesting. I would recommend this book to teens/adults who enjoy a small adventure with their romance and wonderful descriptions of not just one couple but three and also three countries, France, England and Germany. I received a copy of this through netgalley from the publisher and the opinions are my own. Thanks

Oh. My. God. How have I never read anything by this author before?!
It’s been such a long time since I read a book that kept me engaged throughout, that told a love story but also held me captive with it’s intrigue. I think that Frankie and Reynard might be one of my favourite hero and heroine duos ever and the secondary characters are all amazing! I am so looking forward to Sarah’s book, but until then I’ll be catching up on all of Betina Krahn’s other books! 
ARC received from Netgalley in exchange for an honest review

First time I have read anything by this author. She is a great writer. I absolutely loved this book. Frances or Frankie's family is from America, making their money from silver mining . She lives with her mother, Elizabeth and her two sisters, Claire and Sarah. The head of the house is Redmond Strait, their mother's brother. It  is most important to Elizabeth that her daughters marry a titled gentleman. The family knows Reynard Boulton as he is their brother in law's best friend. He is also, known as Fox, since he is someone who knows many secrets. There is attraction between Fox and Frankie but they annoy each other as well. While at a ball, the Duke of  Ottenberg from Prussia notices Frankie and decides he wants to court her. Frankie knows he is not a nice or kind man, but her mother insists that she accept his attention. Fox saved her from him a few times, but Fox has not come into his title at this time and he hasn't enough money or clout to suit Elizabeth. Meanwhile there are other romances happening and a sudden trip to Paris to save a family member. There's a kidnapping, intrigue and steamy love scenes. What an amazing book with different stories woven into Frankie's and Fox's romance. I don't want to give the ending away. Can't wait for the next book. 5+  I received this book from Net Galley and Kensington Books for a honest review and no compensation otherwise. I voluntarily read and reviewed an advanced copy of this book. All thoughts and opinions are my own.
