This was a very entertaining thriller with a unique concept!

We follow heart transplant recipient Rosie Lachlan as she embarks on a correspondence relationship with her heart donor’s husband, local famed author Morgan Thorne. Rosie starts developing feelings for Morgan. Has Rosie found her soulmate?

There were plenty of twists and turns in this book. Rosie made a lot of questionable decisions! I couldn’t put this book down because I was so interested in where the story was going to go!

It was also interesting learning more about heart transplants and the everyday difficulties that exist for a person who has had a heart transplant. I really sympathized with Rosie and her daily struggles.

I would recommend this book to anyone who loves twisty thrillers that keep you constantly guessing about what’s going to happen next. Every time I thought I could predict an outcome, something else would happen that would throw me off completely!

Thank you Atria Books for providing this book for review consideration via NetGalley. All opinions are my own.

When I read this book's description, I knew I had to pick it up. It’s about a heart transplant recipient convinced she’s destined to be with her donor's husband.
Rosie, the main character, is utterly unhinged. Her actions and the twisted rationale behind them were so delusional that I couldn’t look away.
I love an unreliable narrator, and this book hooked me from the very start. I foujd myself flying through part one.
When I got to part two, I found myself dragging a bit. The phrase "Rosie-colored glasses" felt overused, and the conclusion turned out to be a bit predictable.
That said, if you're looking for a quick, binge-worthy thriller with a unique storyline, this one is worth checking out!

Thank you so much NetGalley and Atria Books for the advanced copy of this beautiful book in exchange for an honest review.

This book was a unique and wild ride.

Part 1 had me thinking Return to Me (one of my favorite romance movies from the early 2000s starring Minnie Driver) meets a thriller (my favorite genre). Rosie receives a heart transplant and through Donor Connect connects with the widower of the heart she received, and she finds out his identity before he finds out hers (are you picking up the Return to Me vibes yet?? Megan did you find inspiration from this movie or am I just picking up things? lol). You see their connection growing not only through these exchanges but also the emails Morgan wrote to his best friend. There is speculation that the famous author Morgan had more to deal with the death of his wife than meets the eye and as Rosie dives deeper into her feelings for Morgan and her self-investigation into the death of Daphne (that resulted in saving her life with the donation of her heart) you are left with yet another death! The murder of Morgan that is called in by Rosie herself.

Part 2: oh the twists and turns you have in the second half of this book! I was left clinging to every turn trying to figure out who to believe. The growing unreliability of Rosie, the borderline stalking as more light is shed on to the emails of both Donor Connect as well as the ones sent from Morgan himself. You are left trying to figure out who killed Morgan and the character I thought was responsible from the start---let's just say I was shocked when the truth was revealed.

I will be thinking of this book for a while and will definitely be recommending it to those who loves thrillers as much as I do.

Also side note- as someone who has been frequently called too much...it was nice to read about a character who deals with the same (although maybe to a more extreme nature ;) )

After receiving a heart transplant, Rosie begins corresponding with the widower of her donor via an anonymous online portal. She starts to fall for him, but then she begins to wonder if his wife's death was an accident. Engrossing and twisty! I enjoyed it a lot.

Thank you to NetGalley and Atria Books for the ARC!

This was my first 5 star read of 2025. This fast past thriller had love and intrigue throughout. The man Rosie messages at night is a writer named Morgan. His emails are golden after all he has written many thrillers. With her new heart, she falls in love. What she doesn’t know is what parts of her have fallen, and what he doesn’t know is her little secret, for now. Thanks for netgalley and Megan Collins for an advanced copy read.

In this twisty thriller, Rosie is recovering from both a heart transplant and a broken heart from a failed relationship. She connects with the husband of her donor through an online service called Donor Connect, who is a famous author. She finds that they have a surprising amount in common and begins to wonder what a future with him might be like.

This book is full of twists, turns, and red herrings and moves at a fast pace. Just when you think you know what’s happening, you realize that you are completely wrong. I thoroughly enjoyed the Friends and Taylor Swift references sprinkled throughout, as well as how the author integrated the crazy ex girlfriend theme into the story in multiple ways. The unreliable narrator comes into play in this story as well, which I always enjoy in thrillers. My advice is to go in blind and enjoy the wild ride!

Thank you to Meghan Collins and Atria books for the arc and opportunity to be an early reader and reviewer.

I thoroughly enjoyed this crafty psychological thriller. It has an original and compelling plot with a sufficient number of red herrings and twists to keep it exciting enough in the first half of the story to carry it through to the end. It was a quick and entertaining read. I would definitely read future books by this author and recommend this book to all suspense seeking mystery/thriller fans.

My sincere thanks to NetGalley and Atria Books for giving me the opportunity to read a DRC of this gripping story in exchange for an honest review. All opinions expressed are my own. I will be posting my review immediately to my Goodreads account and to Amazon and Barnes&Noble on the publication day.

This was my first book by Megan Collins and I really enjoyed it! It’s a mystery/thriller about Rosie Lachlan, who has had a history of being a little obsessive in her relationships. She ends up having to have a heart transplant and starts communicating with her donor’s widower. History is starting to repeat itself as she becomes obsessed with knowing every detail about him and becomes more than a little...unhinged.

The book is told in two parts. I felt like part one hooked me from the very beginning, was super fast-paced, and was wild how unhinged Rosie is as a character. You also start to realize she may not be the only unhinged character as the story goes on. Part two was a little bit slower paced for me as it turned more mystery than thriller. For the first few chapters into part two there’s a twist where I was like, wait….what??? So you need to very, very carefully read part one :)

Overall I thought this was a solid mystery/thriller and if you like unhinged female characters in your thrillers I think you’ll really like this one!

Thanks to NetGalley and the publisher for the eARC copy in exchange for an honest review.

This was so unhinged!!! Could NOT put this book down. I mean, with that premise you know you are in for a wild ride. I'd love to know what the audio is like for this one!

Rosie is determined to live her life now that she has a second chance. After a successful heart transplant and back working in her parent's bridal salon, she is focused on finding her forever. Breaking up with her boyfriend/fiance Brad left her heartbroken-and then her heart truly broke-leading to a transplant. A year after the transplant, donors and recipients are allowed to connect online. Rosie quickly realizes she's received the heart of a very popular writer's late wife. While they're supposed to leave out personal details, Rosie and Morgan soon dive deep into their personal lives and Rosie seems convinced she and Morgan are meant to be together. However, some details emerge that cause Rosie to think Morgan may have been responsible for Daphne's "accidental" death. When Rosie's friends and family express concern for some of her behavior, it is clear Rosie has always been very fixated on her boyfriend's-to an unhealthy extent. When shocking events occur, Rosie finds herself in danger-and nearly alone-as her family and friends start to suspect the worst. Told through alternating perspectives, readers will discover some crazy twists and turns and also question Rosie. This was a fast read and the Taylor Swift playlist was a fun accompaniment, 3.5 stars rounded up to 4.

Thank you to NetGalley and the Publisher for this ARC in exchange for my honest feedback.

This had good pacing and lots of twists and turns, but it deviated from the synopsis a lot, so it wasn’t really what I was expecting. Still kept me engaged and the ending was great.

There were so many disturbing moments here and some that were relatable to finding The One (or who we think is The One at least). Full of creepy disturbing moments and moments that made me laugh.

I've read all of the books by this author before, and while this one wasn't my favorite (that would The Winter Sister), it was a fun, character-driven read! Swifties will appreciate the nods to Taylor Swift's themes and songs, and there's a great twist about halfway through the book. It feels modern and touches upon some important ideas in how we as a society frame women in relationships that ultimately fail. It got a little too cliche-y with some dialogue towards the end during the reveals, but overall, it's thoughtful thriller with a flawed and lovable main character.

Cross My Heart by Megan Collins
⭐️⭐️⭐️⭐️/5

Yes!!! This book blew my mind. I was so hopelessly hooked and it kept me turning the pages during my road trip. I have loved and liked previous works by this author, but this one hit it out of the park. I loved the way the book was formatted with both text and email conversations, which were easy to read but provided a lot of information. The only thing I think I would have loved to see was a viewpoint chapter from the heart transplant donor herself. Maybe in a flashback entry or something.
Either way, what a top-hit thriller 👏

#qotd I've been out a bit - and will continue for a couple more days here. I just had to drop in and review this book!
What have you been up to this past week?

Thank you NetGalley!
This is a book about a unique woman who had a medical procedure who changed her life. It was a little slow at times but I liked the suspense and mystery. It was a little unbelievable but I don’t mind that with thrillers. I would recommend this book to people who want an interesting thriller with an unreliable narrator.

What a twisty read, book peeps!! Lots of unhinged females in this one too!! Maybe a few too many? 😅

The twists were great though, and I didn’t figure out who our bad guy/girl was until the very last moment! Definitely recommend this twisty thriller! 👏

Thank you to NetGalley, Atria, and Megan Collins for the opportunity to read the eARC in exchange for my honest review!! ❤️

Rosie is rebuilding her life after personal and medical troubles when she decides to reach out to the husband of her donor's heart--famous writer Morgan Thorne.

This was such a good thriller! Here's what I loved:

Rosie: Yes, she's a mess. But I honestly loved her. She is a true anti-hero because she really is her own worst enemy. But I still was rooting for her the entire time.

The Twists: This one is twisty. Just when I thought I knew where it was going, it went in a different direction. It helps that everyone is so flawed in this book. You really can't trust anyone.

Overall, this was a really great thriller!

Thank you to the publisher and author for the gifted copy!

I was hooked by Cross My Heart by Megan Collins right away. I found there was just the right amount of mystery, heart, twists-and turns, and the pace was fantastic. I loved the mixing of emails and prose as well.

One of things I appreciated is that just when I thought I had it figured out, there was a new turn. The twist into the second half literally made me sit of in bed. I loved it. There were great hints along the way to make the ending make sense but it wasn't blatantly obvious (to me) until quite later on.

There were moments that felt a little too cheesy to me and sometimes a pop-culture reference that made be cringe just a bit, but that's my own personal preference. I had a lot of fun reading this and will definitely pick up more Megan Collins in the future.

I’ll never get over how much I 💕HEARTED💕 this book!

There were twists and Taylor-coded Easter eggs galore AND some of the most memorable characters that I’ve read this year!!!!

It was so good that upon finishing at 2am I had to force myself to go to sleep when all I wanted to do was commend @megancollinswriter for the brilliant book that truly captured my attention from start to finish!!!

5.0⭐️ (even though I wish it could be more)


⭐️CROSS MY HEART, out January 14th⭐️

Thank you to @atriabooks @atriathrillers for the wonderful gifted review copy of this book #atriapartner

This was a fantastic ride! I have not read from Megan Collins before, but this will definitely not be my last book of hers. A heart transplant recipient becomes infatuated with her donor's husband and finds out all she can about him. The pace was perfect for this- I was never bored- and I also never knew who to trust. This had the perfect amount of entertainment and depth- I just wanted to hug our main character! Great read.
