Jessica Patch brought psychological thrillers to the genre Christian fiction and her latest The Other Sister doesn’t disappoint.
Charlotte Kane has lived a life that many children in America have unfortunately had. She was born to an addict single mother and ended up in foster care where her best friends also lived tragic lives. When she finds out she has an identical twin that was adopted into a wealthy family and is not a famous influencer, she knows she needs to meet her. Her life takes an even darker turn after their meeting. In true thriller pattern, no one is who they same to be.
The darkness in this novel was hard for me at times, but it is a compelling story that one can’t stop reading.
I received a complimentary copy thanks to Harlequin and NetGalley, but all opinions are my own.

Wow! This book was amazing! I’ve read and loved lots of Jessica R. Patch’s books, but in my opinion, this is her best yet. I couldn’t stop reading, yet I didn’t want it to end! I had to keep making myself stop, so that I could enjoy it just a little longer. This thriller had me riveted. The characters are so well-written and jump off the page. I loved Charlotte with all of her deep-seated issues, and she wasn’t the only one with issues! Those “issues” are what makes this novel so unpredictable and twisty. You never know what they’ll do next. I was completely stunned! If you’re a fan of thrillers, you’ve got to read The Other Sister! It’s one I’m going to read again and again! I highly recommend it! 5 huge stars!!!

I voluntarily reviewed a complimentary copy of this book. All views expressed are only my honest opinion.

I read a lot, and I also read across a wide range of genres. Psychological thrillers aren't always my favorite, mainly because if a book is labeled "psychological" I expect certain things in that genre - an unreliable narrator, crazy plot twists, and not knowing what's happening at any given point in the story until the end when the pieces fall into place. Most seem to fall short for me - maybe it's a great story, but it doesn't seem to have that edge that gets in my head and makes me question my own sanity along with the characters'. But Jessica R. Patch nails the psychological thriller with The Other Sister. This is what a psychological thriller should be!

We have Charlotte, and she's a bit unreliable. We know she tries to be good, but has a dark past and is known for pretending to be someone she isn't. When she discovers that she has a twin sister, rich socialite Acelynn, Charlotte winds up assuming her life. But what she finds is that Aceylynn's life is complicated and very dark.

We also have lots of plot twists. The story took me down several paths only to leave me with whip lash. I couldn't possibly guess the ending. The characters are all a bit unhinged and any one of them could be the bad guys of the story. I love Jessica's story telling abilities and they way she reveals just enough information to string me along until the payoff at the end. And it's a fantastic ending. This isn't a traditional romantic suspense where everything is wrapped up neatly with a bow by the end. This thriller will have you thinking about the story long after you've put the book down. Get ready to binge read in one sitting!

I received an ebook review copy of this book through NetGalley. All opinions expressed in this review are my own.

Readers who like psychological thrillers will enjoy this twisted story. Charlotte has had a rough life bouncing from one foster home to another. When her drug addict mother dies of an overdose, Charlotte finds out she has an identical twin sister who has a perfect life. But things don’t always appear as they seem. Lots of dark secrets drive this tale to a surprising conclusion. Recommended.

In "The Other Sister", Charlotte is barely keeping her head above water in Chicago when her abusive mother passes away. While sorting through her meager belongings, Charlotte stumbles across a photo that sends her world into a tailspin: she has a sister. An identical twin. Her twin was raised in Savannah among wealth, privilege, and public attention. Acelynn is everything Charlotte isn’t — successful, polished, and seemingly living the dream. But dreams can be deceiving.

When the two sisters finally meet, their lives are irrevocably changed. What begins as a story of reunion quickly turns into a tense, emotionally layered thriller that explores the stark contrast between two upbringings — one shaped by struggle, the other by superficial luxury hiding deeper scars. The narrative takes a shocking turn when a twist of fate forces Charlotte to assume Acelynn’s identity. What she once envied becomes a suffocating masquerade as she discovers just how many secrets are hiding behind Acelynn’s carefully curated life. Deception, manipulation, and danger seem to lurk around every corner. No one in Acelynn’s world is who they claim to be — and the deeper Charlotte goes, the harder it becomes to escape.

The novel is rich with atmosphere and tension. Characters are vivid and multi-dimensional, constantly evolving in ways that keep you guessing. As Charlotte navigates a world filled with betrayal and buried truths, the story builds toward a final act packed with a new curveball in each chapter — and an epilogue that delivers one last unexpected punch.

"The Other Sister" isn’t just a psychological thriller it’s a smart, emotional exploration of identity, trauma, and the shadows that often lie beneath beauty and wealth. The pacing is relentless, with no room for boredom as the story hurtles towards its unpredictable conclusion. It’s gripping, surprising, and impossible to put down.

Thank you to NetGalley, Jessica Patch, and Harlequin for an ARC in exchange for my honest review. All opinions are my own.

"Truth hidden in darkness always comes to light, and secrets with it. Sins always find you out."
The Other Sister is a story full of surprises and secrets, hard to put down as the story unfolds. It begins with Charlotte, living in Chicago, who finds out when going through her deceased drug addict mother's things that she has an identical twin, Acelynn ,who was adopted into a wealthy Savannah family. . The two get together in Chicago but things go deadly for Acelynn with bad guys and Charlotte flees to Savannah to escape and becomes Acelynn. Did she escape one scary situation to move to another? Acelynn's friends and family are a narcissistic group of people full of unbelievable secrets and twists. Just when you think you have an idea of who did what, you have it wrong. A serial killer is on the loose on top of everything else. Evil lurks in the darkness but how can Charlotte brings events into the light and not cause problems for herself. Who would believe her? I hope that there is another book as this one left some dangles. Outstanding read.
I received a copy in exchange for an honest review. These are my thoughts.

4.5 stars - One of my favorite reads of 2025 so far!

Patch crafts a perfect example of a twisty, gritty psychological thriller designed to keep readers on the edge of their seats and turning the pages. While there is a Christian theme, it is minimal, so keep that in mind when reading this. There are multiple twists, and the tension and suspense are strong from the get-go. The characters are multilevel and realistic. The story demonstrates that while you may get a new chance In life, that doesn't totally erase your past. It also shows that everyone has their secrets. I look forward to reading more books from this author.

Possible trigger warning: abuse, abandonment, violence, manipulation

NOTE: This is geared a bit more to the mainstream audience and may have a bit too many unsettling themes for those readers expecting more of a Christian read.

Oh my word. The Other Sister has to be my new favorite book by Jessica R. Patch. She is the queen of twisty suspense that has weaves in the reminder of God's forgiveness and Grace. Charlotte has had a rough life. She grew up with a mother who abused alcohol and recently passed away. She is shocked to find out that she has a twin that was adopted out. Charlotte becomes obsessed with find out out more about her twin, who she discovers is named Acelynn. On a whim, she reaches out to Acelynn and is shocked that Acelynn wants to come and meet her.,

Then everything goes wrong. She finds out that her friend, Tommy is knee deep in debt to a mafia boss. Charlotte witnesses Tommy's death and runs to Acelynn for help. Acelynn offers to help her and bring her back to Savannah to lay low. However she finds herself stepping into Acelynn's seemingly perfect life.... until it isn't.

This book took me on a journey I was not prepared for. Dark, twisty but with the light of forgiveness shining in. The book is well written, the plot grabs your attention as soon as you start reading. The characters are well developed.

Thank you to the author, publisher and Netgalley for allowing me to read a copy of this book - all thoughts are my own.

What a story! What a ride! This psychological thriller keeps you guessing about what is going on and you truly do not know who to believe. There is a real evil in the story that made me uncomfortable (especially towards the end), but there were glimmers of hope. The journal entries were a great touch and helped tie the story together. I did not see the twist coming at all!

I received a complimentary copy of this book from NetGalley. Opinions expressed in this review are completely my own.

I'm starting to think that author Jessica Patch is a master mind. She is a little scary too as she writes psychological thrillers that keep me guessing. This is one wild book.
I received a copy of The Other Sister from Harlequin and NetGalley. This is my own unsolicited reaction to the book. I've read a lot of mystery/thriller books over the years and this one really got me.
Charlotte Kane has had a rough life. Her childhood in foster care leads her to wish she could have had the life her identical twin sister was fortunate enough to have when she discovers Acelynn Benedict. When Charlotte witnesses the unexpected, her life is turned upside down. Just maybe things can change for the better in her life.
There are shocking twists and turns in this book. It's a solid story for a reader but a challenge for a reviewer. I got so caught up in the plot with its twists and sharp turns. I read into the night but the reviewer in me forgot to take notes. I lost myself in this story of murder, intrigue and shocking actions.
There is also a journal from "Then" written by a mother of young children. She recorded things the one child does because she knows that one is 'not right'. Creepy.
This is listed under Christian fiction. There is a light vein in the story, no preaching at the reader. There are things in the lives of these characters that can and do happen in life. Abuse, greed, terror and thoughts that it's better on the 'other side'. The ending, whoa!
If you enjoy a wild ride of a thriller, you will surely like trying to figure out what is going on here.
This gets a five star from me.

I know the title states The Other Sister by Jessica R. Patch is a dark and suspenseful thriller. However, I didn't realize how much of a psychological suspense it would be. It was much darker than I anticipated, and I got eerie vibes and could not finish. It is categorized as a Christian suspense which is why I requested the read.

Releases Apr. 22nd. I received a complimentary copy of this book. Opinions expressed in this review are completely my own.

Five stars is definitely not enough for this. This is definitely movie quality book. So many twists and turns and the poor mothers in this book! This would definitely be a good Bookclub read. So many topics for a good discussion.
I really cannot say enough good things about this book!!!!

This one took me a while to get into as I found the beginning disturbed me a bit. But once I got about 1/3 of the way through, I couldn't put it down. It was incredibly TWISTY. I expected some of the twists (perils of being a thriller writer), but others blew my mind.

I love the way the end pointed to Jesus and His saving grace, but also had a character who reflected Christ's love, mercy, and grace.

If you enjoy psychological thrillers, you'll definitely want to give this one a read.

Suspense!! This story was fascinating--unlike anything I’ve read before. It was under the Christian fiction, but it definitely isn’t a Christian or faith-filled novel. But, it was good. There was a bit of eeriness to it and lots of darkness and evil. Not for the faint of heart. I was not expecting all the twists and turns and ending floored me—which I think made it better.

Wow! This was a very dark and intense psychological thriller. The identical twin trope used here is to explore nature vs. nature. One twin adopted into a life of luxury, and the other is a product of the foster care system, now living a life of poverty.

There is non-stop action in this novel, with a serial killer on loose, family drama, no one is who they seem to be, and a mysterious evil child at the center of it all.

The characters have layers with compassionate and terrifying personalities. The foreshadowing creates an atmospheric sense of unease and foreboding, and the lies, secrets, and betrayal make this an unputdownable thrilling read.

With themes of light vs. dark, envy, abandonment, and undertones of faith throughout the book,there is absolutely something for everyone here.

• Rich vs. Poor
• Gaslighting
• Secret twin
• Sinister plot
• Mental illness
• Addiction

Thank you to @jessicarpatch, netgalley, and Harlequin-romance. My reveal voluntary.

I cannot believe I actually loved reading this book with some of the sickest and most evil characters I have ever encountered. And the twists – apparently I was allowed to figure out some of the twists by the extremely clever way the book was written only to find out that they were really not the ultimate twist. And then I read the epilogue. The Other Sister is definitely a roller coaster ride full of darkness and then a thin glimmer of light. I had no idea it was listed as Christian Fiction, and I am totally confused about that label. But I am glad I didn’t know because if I had I would never have picked it up.

I grabbed this book from this author expecting it to be a romantic suspense. When I found out it was going to be a psychological thriller, I was a little wary but I’ve greatly enjoyed other books by this author.

A lot of this definitely turned my stomach a bit. Playing up the inherent evil in all of us but starting with someone at the age of a toddler was not a good feeling. I’ve always been fascinated with the psychology on identical twins separated at birth and how they often are mirror copies of each other in looks and life and loves. This is definitely NOT that.

This is definitely a psychological thriller. And one that deals with a ton of darkness and evil on multiple different levels. I’ve read books from her before that kind of flirt with the line, but this one feels like it crossed fully over. I heard that the faith element would be more toned down, but quite honestly, it was really nonexistent. I think I’ve read more faith elements contained in secular mainstream thrillers than this one. This was a mainstream psychological thriller. It was clean, without the swearing and explicit content and gore, but it read like a mainstream thriller.

I rounded this book up to a four, because the last section of the book had a lot of twists and turns that upped my rating and review of it. However, I would not pick up another one like this again. It would have rated higher as a pure mainstream thriller but I was expecting more from the Love Inspired line. The whole evil in all of us is a true idea, but I felt this was lacking the explicit Light that was needed to balance that, and I felt like the lack of that explicit Light – faith – was a glaring issue and made the book fall short of what it could’ve been had faith been a prominent part of it. 3.5 stars rounded up to 4.

I enjoyed this book. It definitely kept me on the edge of my seat and wanting to know more! I liked the twists and turns that this author has in her books. Will definitely read more from her!

The Other Sister by Jessica R. Patch

𝗤𝗨𝗜𝗖𝗞 𝗣𝗟𝗢𝗧 𝗣𝗘𝗘𝗞
Charlotte Kane discovers she has an identical twin, Acelynn Benedict, who was adopted into a life of wealth and privilege. When tragedy strikes, Charlotte steps into Acelynn’s world - only to find herself tangled in deadly secrets where no one is who they seem.

𝗛𝗢𝗡𝗘𝗦𝗧 𝗢𝗣𝗜𝗡𝗜𝗢𝗡
The story alternates between Charlotte’s perspective and a mysterious journal written by a woman who believes her daughter is a psychopath. These journal chapters were some of my favorites. I loved the intrigue and guessing how it related and who was who.

Acelynn’s wealthy, awful family and friends were fun to read about, but her internal musings sometimes slowed the story down. Some of the reflections felt repetitive, and I found myself wanting more action, less thoughts.

The ending sped up and there were so many twists I didn’t see coming which was fun, and I really enjoyed the final scene!

𝗪𝗢𝗥𝗧𝗛 𝗧𝗛𝗘 𝗥𝗘𝗔𝗗?
If you love messy rich people and the secrets they hide, this one’s for you. And if you enjoy a lot of introspection in your thrillers - plus the shenanigans of someone stepping into another’s life - run to read it!

Thanks to @Netgalley @HarlequinPublicityteam and @HarlequinAudio for access to this advanced readers copy

A psychological thriller with some edge of the seat moments. Suspenseful with twists and turns that kept it unpredictable all the way through to the end. Definitely unique characters, with a glimpse into the life of a person who experienced less than ideal foster care and a drug-addicted parent. It takes a candid snapshot of families who look perfect on the outside but hold terrible secrets underneath. The web of deception and lies is a trap for Charlotte, but a ray of light shines through the dark with a bit of hope and redemption at the end.
Readers who like suspenseful mysteries with an edge may like this one. Better for mature readers due to subject matter. 4.5 stars
