This book was a slow, but consistent page turner. The plot and pacing were very good. I love a good sister book! There were a few twisty turns in there to keep you turning the pages. I enjoy a book that keeps you guessing. Thank you for allowing me to review this book.

Family drama at its finest…

This is as suspenseful, shocking, twisty. I enjoyed it a lot. The only thing I didn’t like was that there were way too many characters. I kept getting confused about the story at some parts because of how many people were involved in with what was going on. Other than that, it was a great read. It was one of those books where you’ll never guess the ending.

Thank you to the publisher and author for letting me read and review this book

Thank you NetGalley and publishers for the opportunity to read this ARC. Definitely a slow burn. There were a few exciting and interesting points in various parts of the story. An overall good read.

The Wrong Sister by Claire Douglas is about two sisters who "swapped" lives/houses for a week so Tasha and Aaron can have a relaxing break from their twin daughters. But their break is stopped short when Alice and Kyle were victims of a house break-in, which left Kyle dead and Alice with a head injury. As the investigation goes on, family secrets are unraveled and the mystery of their long lost sister Holly is brought to light again.

This mystery/thriller had me hooked from the beginning. There were a couple of complex little side plots but it all tied in at the end mostly. I've read enough thrillers to see some of the twists and revelations coming. I thought the characters were well-developed. I would've given the book 5 stars, but there was one unresolved mystery that left me unsatisfied. However, the entire book took me on a journey of suspense, mystery, secrets, and confessions. It did not disappoint.

Thank you to NetGalley, author Claire Douglas, and publisher Harper Paperbacks for providing me with an ARC, in exchange for an honest, unbiased review.

I LOVED this book-it was face paced, interesting, twisted and I couldn't out it down. I loved the story being told from multiple point of views, but liked that they primarily stuck with Tasha's perspective.

I enjoyed the mystery element, as well as the family drama that was going on throughout the book.

I enjoyed this book. A great twist on a thriller/mystery. I thought the characters were well developed. Writing flowed easily.

This book was brilliant. Took me two days to read, couldn't put it down. The characters were really strong,they faced some decisions I wouldn't like to make. Plenty of twists, lots of thinking you know what happened only to find you don't. No spoilers or plot descriptions, if you like books that grip you from the start this is for you.

Thanks to the author, publisher and NetGalley for the ARC of this book in exchange for my honest opinion.
I've read many of Douglas' books and this one is very similiar. A slow burn that kept me reading. I really enjoyed the characters and their relationships.
This is another fantastic read from the author. It is a tense gripping and quite complex thriller, and the authors is great placing some red herrings to keep you guessing throughout. I hadn’t figured anything out until the conclusion of the story with the author’s trademark twist at the end. 5 stars from me.

Michelle Frances delivers a gripping psychological thriller with It Was Supposed to Be You, a novel packed with suspense, family secrets, and jaw-dropping twists. 📖🔥 From the very first page, I was hooked by the intriguing premise—two sisters who seem to have it all figured out, until one fateful night changes everything.

What I loved most about this book was the way it explored sisterhood and trust. 💔👭 Tasha and Alice’s relationship feels real—filled with love but also underlying tension, making their dynamic all the more compelling. The shocking attack on Alice and her husband raises countless questions, and when the ominous note arrives—*"It was supposed to be you"—*the tension skyrockets. 😱✉️

The mystery unfolds at a relentless pace, keeping me on edge with each new revelation. 🔍⚡ Frances masterfully builds suspense, making me question every character’s motives. Just when I thought I had figured it out, another twist hit me out of nowhere! The writing is sharp, the emotions raw, and the stakes incredibly high.

If you love fast-paced psychological thrillers with deep family drama and dark secrets, It Was Supposed to Be You is a must-read. ✅📚 It’s an electrifying ride that will keep you guessing until the final page. Highly recommended! 👏💀✨

This box was sensational, mind blowing and kept you hooked from beginning to end. It was a who-done-it type of book. I highly recommend reading it!

I LOVED this book. The perfect thriller that kept me on the edge of my seat wanting to know what happens next. I will definitely be reading more books by Claire after this.
Thank you to NetGalley for allowing me the chance to read this book for free in turn for a review. #Goodreads

The Wrong Sister by Claire Douglas is an engaging suspense-filled mystery/thriller book. I enjoyed the storyline, the multiple POVs and the several twists. I didn't see the ending coming and the twist at the end was brilliant. I received the ARC from Harper Perennial and Paperbacks via Netgalley. This is my honest review.

3 Stars

I really enjoyed this book overall. It kept me engaged, and while I was able to guess some of the twists early on, there were a few major ones that took me completely by surprise. The pacing was great, and the plot was well-crafted, with just the right amount of suspense to keep me turning pages.

Note: Thank you to the author and publisher for providing me with this ARC.

A fast-paced, absorbing mystery that seamlessly blends family secrets, tragedy, murder, and the complicated ties between sisters. The story unfolds mainly through Tasha’s eyes, but we also get perspectives from her sister Alice, their mother Jeannette, and even brief glimpses from the baby sister who vanished years ago.

The pacing was one of the novel’s strongest elements—it kept me hooked from start to finish. This is the kind of book that refuses to be set aside; DNF (Did Not Finish) won’t even cross your mind. At its heart, the story revolves around two major mysteries: the disappearance of baby Holly and the murder of Alice’s husband, Kyle. Are these events linked or simply two tragedies colliding? You’ll have to keep reading to find out.

Though the mystery kept me intrigued, the novel leaned heavily into the family drama. The tension between Jeannette and her daughters felt raw and believable, with each character struggling under the weight of their own unspoken emotions and hidden pasts. While this added depth to the story, it did sometimes push the mystery into the background.

The ending, did in fact shock me. The thriller aspect managed to keep some of its edge even toward the conclusion, especially when one of the major revelations was revealed rather suddenly. The opening scene in Venice was one of the book’s highlights—tense, immersive, and cinematic, with Tasha desperately fleeing a knife-wielding pursuer through the city’s winding streets. I only wish the novel had spent more time in that high-stakes atmosphere before shifting to the slower-paced police investigation back home.

Overall, this book was a 4 star read for me.

This was the first novel by Claire Douglas that I have read and I was not disappointed. Two sister's do a life swap for a week until it goes horribly wrong...

I wish the suspenseful parts were more intense. I think some character development would have helped to get the reader more involved.

Great book! There were some good twists that kept you guessing. It read well with the chapters being from different characters.

This story masterfully intertwines themes of trust, betrayal, and the complexity of family dynamics, keeping readers hooked from the first page to the last.

The novel centers on the protagonist, who becomes increasingly entangled in her sister's mysterious and sinister secrets. The characters are layered and nuanced, each one making you question their motives and reliability. Douglas does an excellent job creating tension, with unexpected twists and red herrings sprinkled throughout, ensuring that readers stay on edge.

What makes this book particularly compelling is its exploration of sibling relationships and how the bonds of family can be both a source of strength and vulnerability. The pacing is swift without sacrificing depth, and the alternating perspectives keep the narrative fresh and engaging.

While the ending ties up most of the loose ends, some readers might find it slightly rushed or wish for deeper closure on certain subplots. However, the journey itself is so gripping that it more than compensates for these minor shortcomings.

If you’re a fan of psychological thrillers that delve into the darker sides of family and trust, The Wrong Sister is a must-read. Claire Douglas continues to prove why she’s a powerhouse in the genre.

Thank you to netgalley and the publisher for an advanced copy.

Tasha and her husband have twins and need to romantically reconnect. So her sister and brother in law offer to let them stay at their place for a week while they watch the twins.

Romance is in the air. Until they get a frantic phone call and life as they know it will never be the same.

So many twists and turns. Family drama. Betrayal. And lest we forget…murder.

This book had it all and I loved it

This was such a good book. I would have to say 4 stars for sure! It was a quick read only took about 2 days. I have only read on other by this author and I loved it too. So please join Alice and Tasha on their journey you will enjoy it.
