Cross My Heart was a fast paced, quick read that was perfect to get me out of the reading slump I've been in! Once I started, I finished within 24 hours. There were plenty of twists that I didn't see coming that kept me engaged and needing to keep reading to see how the story ended. Rosie is the main character who discovers that the heart she receive via transplant was from the wife of a famous author, Morgan Thorne, that also happens to live in her town. Rosie and Morgan begin exchanging emails via DonorConnect anonymously, but Rosie's figured out whose heart she has and starts wondering if this may finally be her shot at true love. From there, the twists and turns don't stop until the end and when I thought I'd have everything figured out, I was wrong and I loved it for that reason.

Thank you to Atria and NetGalley for the ARC in exchange for my honest review!

I was pleasantly surprised by this one. Cross Her Heart is a great popcorn thriller—fast-paced, twisty, and super easy to get lost in. I thought I had it figured out more than once, but nope… the twists kept coming.

If you like thrillers with buried secrets and characters you’re not quite sure you can trust, definitely give this one a shot.

Meet Rosie Lachlan. She's dealing with a failed relationship and is a heart transplant recipient. After suspecting her donor is Daphne Thorne, Rosie uses DonorConnect, an anonymous platform, to connect with her donor's husband. Turns out her donor's husband is an author named Morgan Thorne. Through their email communication, they learn more about each other. Soon, things spiral in Rosie's mind, and she becomes convinced she and Morgan are meant to be together. As Rosie learns more about Morgan and his relationship with Daphne, rumors start to swirl, and Rosie becomes increasingly suspicious about what really happened to Daphne. What happens when heartbreak becomes an obsession? Is Morgan the man Rosie has been waiting for, or should she stay away?

I enjoyed this story! It immediately grabbed my attention and kept me guessing the entire time. I had some theories, but I definitely didn't see the ending coming. Rosie's story was interesting, and it was fun having the story told from her point of view. Was she unreliable? Absolutely! I loved trying to figure out what was imagined and what was real. This psychological thriller had me deeply involved and on the edge of my seat. I felt the story flowed well, and I loved the mediums used to tell the story. From the thriller book excerpts to the various email exchanges, text messages, and multiple points of view, I was all in. Rosie's "crazy in love" antics made this book hard to put down.

Than you Atria books for my gifted copy in exchange for an honest review.


This was a super slow burn. Normally I enjoy emails to break up the story, but these were a little long. The long chapters didn’t help either. I need short engaging chapters. I wasn’t super invested until the second part of the book. It did make me rethink everything I read in the first part, but not enough to go back and read.


The Taylor Swift nods were entertaining. The Prophecy is one of my favorites of hers.

I finished this in about 24 hours!! It kept me guessing until the end, although pretty much all of the characters were unlikeable to me. That tends to be a common theme for these types of books though. Thank you NetGalley!

4.5 - “She has his dead wife’s heart; the one she wants is his.” Ooohhh Cross My Heart was just the type of unhinged book I needed. I loved it! Surprisingly, this was my first time reading something written by Megan Collins but now I want to go back and read more from her. Go into this with as little knowledge as possible and you’ll be so happy that you did! It’s so fun, entertaining, and had an original concept which can sometimes be a tricky thing to accomplish in the thriller world.

Thank you Atria for providing me with a copy through NetGalley.

Binge worthy!!! This book got me out of a reading slump immediately! Finished it so quickly and I’m obsessed!

I love an unreliable narrator, morally gray characters and unhinged MCs and this book absolutely delivered!
The premise was so good, the twists kept me on my toes, and I simply had so much fun reading this book!
I can’t wait to read more books by Megan Collins. I’m a new fan!

I started this book but was unable to complete it as I felt it was slow paced for me and I could not engage in this. The premise of the story was too much for me which I thought I would enjoy but I found off putting as I read and introduced asap.
This book was not for me but I appreciate the ARC NetGalley and Atria Books

Cross my heart was such a twisted little domestic thriller! Rosie has never given up on looking for love. One year after her heart transplant, she's looking for connection and decides to contact the widow of her heart donor. The donor happens to be Morgan Thorne, successful author and local celebrity. As Rosie gets to know Morgan even more, soon things take a weird turn.

This was such a fun and well-written thriller. I was immediately drawn into the story and fully invested, but then when that twist happened at the halfway point? Wow! I read a lot of thrillers and always spend too much brainpower trying to figure out the twists (hi, I'm the problem, it's me), so it's not often that I'm completely surprised by things.

I really had so much fun reading this book and Megan Collins is definitely an author I will continue to read from in the future.

Thank you so much to Atria and NetGalley for a review copy.

I loved this one. It was like a medical thriller version of Misery, but both sides aren’t to be trusted.

This is my second Megan Collins book and I like the absolute “WTF” brains that she gives her characters. The unhinged personalities are top tier. But beyond that, she gave us a truly captivating story as well. I haven’t seen a thriller with this particular approach, the donor angle was a way to keep the stalker/obsessive trope fresh.

As before, I look forward to seeing what Megan comes up with next…and in the meantime, diving into the three books I have marked to-read on Goodreads!

This book was absolutely wild in the most psychologically messed-up way. Rosie’s journey—especially with the heart transplant twist—was both fascinating and unsettling. The tension between her and Morgan kept me on edge the whole time, especially with the darker rumors surrounding him. The whole story had such an unpredictable vibe, which made it a thrilling, if not unsettling, read. Plus, knowing the author is local just added an extra layer of intrigue for me. Definitely not your typical romance!

I haven't been in much of a thriller mood lately, but Cross My Heart totally surprised me in the best way. The premise felt fresh and unique
-something about it just hooked me right away. Even though the ending was a little predictable, the journey getting there was full of twists and turns that kept me going.

What really made it stand out for me was the romance subplot. It added just the right amount of emotional depth without taking away from the suspense. I found myself just as invested in the characters' relationship as I was in the mystery unfolding around them.
Overall, it was a fast, fun, and suspenseful read. I think this mood will definitely appeal to the mood readers like me who crave a little bit of everything!

Thank you to NetGalley & Atria for the eARC!

This was the first book I had read by this author and I enjoyed it. Good character development. Will be reading more from her.

Rosie receives a heart transplant and becomes infatuated with the husband of the donor. A domestic thriller filled with so many twists and turns you won't be able to put it down!
I loved this book. Dare I say it's my new favorite Megan Collins read?! If you're looking for a fast paced thriller to suck you in, this is the one!
5 stars!

thank you to netgalley for the e-arc. collins is one of my go-to thriller writers and i was looking forward to this even before getting an arc. this one particularly reminded me how fun it was to read gone girl the first time. there was so much going on but it never lost the plot or twists.

I absolutely loved this book! From the Taylor Swift-inspired dedication to the unhinged storyline, I was thoroughly entertained! 4.5⭐️

I was so hooked on this book, I grabbed a library copy and was asked by a dozen coworkers about it. The cover is captivating. Here’s the good….. totally gripping, unreliable narrator, at some points during reading I thought is Rosie insane… or am I??? The first twist was great, the reveal… excellent. The ending, totally lackluster and takes from the potential. Literally the only ending I didn’t want is what it was! This would have been a 5 ⭐️ if the ending was different. I can’t give it away but totally silly ending for a book that sucked me in and held me tight for the entire ride. How could you?????

A twisty novel about a heart transplant patient that becomes obsessed with her donor’s husband 👀

I mean, do I really need to tell you more?? Because that’s all I needed to hear to pique my interest! From the very first chapter I was hooked.

Rosie is such a complex main character, with many faults. But she is so endearing, it’s hard to not root for her. I often found myself metaphorically wringing my hands because she was very clearly making poor choices, but my heart (no pun intended) felt for her because I could see kind of see why she would do the things she did.

The twists kept me guessing the entire time and I think the ending was done perfectly. I finished the book in two days and it’s been a while since I’ve done that!

Highly recommend! 4.5 stars!

Thank you so much to NetGalley for this ARC!

Rosie is just a woman who wants to find The One. The story takes place about a year after she received a heart transplant that saved her life. And she uses her app DonorConnect to figure out whose heart she received. Soon she figures out that it is that of the wife of a best selling author, whom she is a fan. So she uses the app to connect with him... and uses it as her own personal dating app!

This story had me intrigued right from the beginning. I always found it fascinating. What if a transplant recipient had the ability to take on the personality and interests of their donor? Of course it seemed to be happening in this story but was it really Morgan whom she was falling for? Or was it the idea that she was so eager to find love?

Then the crazy twists happened... and I just couldn't put it down! When I thought I had it figured out I found I was wrong. I really enjoyed this story. The characters weren't super likable to me, but it was interesting to see how the story would play out. It was definitely something a bit different. I really enjoyed this one!!

Megan Collins’ Cross My Heart offers an initially intriguing premise , but its execution falters due to underdeveloped characters, predictable plotting, and sluggish pacing. , The prose remains serviceable but unremarkable, punctuated by stilted dialogue and a rushed resolution that leaves subplots unresolved; though a few scenes deliver genuine tension and the concept’s creativity hints at potential, the novel ultimately feels like a missed opportunity, leaning on genre tropes without offering the depth or originality needed to stand out in the crowded thriller landscape.
