I love everything this author writes! I have met her at a book signing and she is the sweetest person! So i knew i had to try and get this arc! Loved this story and the twists and turns in this book kept me wanting to read! I always try to figure out the end but in this one it kept changing, which I really enjoyed! Was not expecting the ending and will definitely be recommending this book to all my friends! Can’t wait for her next book!

Thank you to NetGalley, Megan Collins and Atria Books for an ARC of this twisty thriller. I can honestly say that there were times where I felt invested in the book, but about halfway through, I was starting to lose interest. I was not particularly fond of the characters and the POV.. maybe multiple POVS would have been better? Not my favourite thriller.

A man whose wife died in an accident reaches out to meet the woman who received his wife’s heart seemed like a great premise. However I figured out a “big” plot twist easily early on and I felt like the end left unanswered questions about the husband which I thought was unnecessarily. Maybe there could have been an epilogue where we learned a little bit about his POV. I’d give it 3.5 stars if halves were allowed and I’d be interested in reading books by this author in the future.

Rosie is just someone who REALLY wants to be loved, okay? And after her last boyfriend broke her heart - literally, she had a to get a heart transplant - she deserves it, right? So she starts messaging her heart transplant donor's husband... And things take off from there. This was a pretty unique thriller with plenty of twists and turns that I did NOT see coming. Points taken off because it lagged a little at times, and Rosie and her "Rosie colored glasses" got under my skin after a while, but overall it is a pretty solid read!

3.5 stars.

This was a crazy ride. There were a couple of twists that sent me reeling and I had to regroup to understand everything that was taking place. There were some very clever moments that had the tension cranked up as if anything could happen...because things kind of went off the rails a bit.

A perfectly enjoyable read and a good plot basis, I had fun with this one. But it does have some issues that lent it to being a more average rated book.

My primary issue: the characters. I really didn't like any of them. There was a lot of whining and self-deprecation and just a whole lot of psychological issues. I didn't feel like the protagonist learned a dang thing and the people around her all had some sort of problem. Is there something in the water in this town? Because everyone is wildly damaged in some way. Obsession is a major issue for a lot of them and everyone seems to be very selfish and insulated. It drove me nuts. I just wanted one person who wasn't a whack-a-do.

Second main issue that prevented a higher rating: The motivation behind the events in the narrative seems a little weak. I mean, I get it, but the set up and background for it wasn't super solid. There was a lot of telling rather than showing, I guess? It just seemed a little thin and didn't really feel emotionally believable. Meh. Maybe I'm just picky.

Anyway...despite my issues with the overall technical merit of the story, I still enjoyed the read. It was fast-paced and interesting and it kept my attention. Not a bad pick for a beach read, travel read, or palate cleanser.

This is one of those books where there are 5-10 suspects and they're all so fucking bat-shit crazy that any of them could be behind the crimes. And are all the crimes related or were they each committed by different people? Well, do learn that, you'll have to read that book.

I've always enjoyed Megan's books and this one didn't disappoint. In fact, it may be my favorite of hers yet!

I loved our MC Rosie. The number of times I was yelling about how absolutely nutty she was. The people in this were so insane as characters! Their choices are questionable at best, but that's what makes it fun!

The plot was twisty and surprising. I was able to guess who the overall bad guy was at about the half-way point but how we got there and the extent of their madness? That was all a fun ride of surprise.

Cross Your Heart has a really intriguing premise that initially drew me in. I appreciated the unique storytelling approach, especially the mixed media format with emails, texts, and other digital communication, which added a fresh layer of depth to the narrative. It helped keep the story engaging and provided a nice variety to the typical format.

The plot itself was twisty and entertaining for the most part, with enough suspense to keep me hooked throughout. There were some interesting developments and moments that kept me curious about what would happen next. However, while the story was definitely entertaining, I didn’t find any of the twists to be jaw-dropping or particularly shocking. Some of the reveals felt a bit predictable or didn't hit as hard as I was hoping for, leaving me with a sense of "okay, that makes sense," rather than being completely taken by surprise.

Overall, *Cross Your Heart* was an enjoyable read, but it didn’t quite live up to the level of excitement I was expecting. It’s definitely a fun read if you're looking for something to pass the time with, but it didn’t leave a lasting impression on me.

This book was so interesting! The way that Megan develops her characters, and the tertiary characters is amazing. I really enjoyed reading this and cannot wait to see what Megan does next. I recommend this book to everyone who likes a good domestic thriller!

Killer book. I have read Megan Collins books before, but I feel certain this one is my favorite! Definitely give this one your time!

Very much enjoyed this! Full of twists I didn’t see coming & fast paced. Would absolutely recommend. Thank you for the early copy Atria!

Megan Collins is great at writing twisty page-turners. This was a solid 3.5 for me. And the main character desperately needs therapy!

It starts with a dedication to anyone who has ever related to Taylor Swift’s The Prophecy 🥹

What follows is a very twisty thriller in which a woman, one year after a heart transplant, starts messaging the husband of her heart donor with the hope of things turning romantic.

💘 this one was so twisty I couldn’t put it down
💗 unreliable narrators everywhere!
🥰 emails, texts, messages, and a narrative has you questioning your recollection and your mind

I don’t want to give anything away, but this one is for you if you’re a Swiftie. This one is also for anyone who has ever been called or made to feel “crazy” by someone they’ve dated. It’s for people who have been gaslit. It’s for people who have so much hope they might get a little ahead of themselves or dream up whole lives that may never come to fruition. It takes the pressure put on women, in particular, to find “the one” and explodes it.

I guessed some of the twists, but my jaw was on the floor at one point!

Cross My Heart by Megan Collins is a thrilling ride start from finish. With so many twist and turns you think you figure out the mystery and then a new layer is added to blow the reader away. This mystery was quirky while pulling at your heart strings while unraveling the story with the main character. By the end I found myself adding Megan Collins to my list of authors to watch for as I picked up my jaw from the floor. Ultimately Cross My Heart was a fun and quick mystery that scratched the murder mystery itch that comes after a mild book hangover.

Heart transplants that come with a whole lot more.
Cross My Heart written by Megan Collins brings a suspenseful story with twists and confusion, perhaps too many. A woman with pink hair and an obsessive personality has a heart transplant after a break-up.
Slowly we learn all the things she did prior to getting sick and it shows she needed help to cope better with the curve balls being thrown at you each day. Fast-forward to learning her heart came from the wife of a famous author, and she died under somewhat strange circumstances. Collins brought in so much drama with double identity and hidden agendas, it became hard to follow when two characters, in some ways, had the same name. Readers can keep track of it, but you still want to know what's really happening. So I found myself both loving and not loving the plot.

Thank you so much for giving me the opportunity to preview this book!!!!

This book goes between emails and present time chapters.

Rosie just gets a heart transplant and she starts to fall for her recipients husband. She starts to wonder what it would be like to be with him. Then the book takes a turn and we don’t know what’s true or in her mind.


This book literally made me say out loud, “What the hell is happening!!?” I loved the suspense and really not knowing what was truly going on!!!
The only thing that was redundant was her constant reenactment of her boyfriend breaking up with her. She was obsessed.

The ending was perfect in my opinion it was great close to the book!!!

I am a huge fan of Megan Collins so i was very excited to receive this advanced reader copy of her newest book Cross My Heart. It did not disappoint! from the very beginning, i was sucked into the story of Rosie and how she is so unlucky in love until she connects with the widowed husband of the woman whose heart she received in a transplant.
She is so desperate to be in love, she has a lot of stalker tendencies that she just sees as her trying to learn as much as she can about her current crush so she can change herself to be their perfect person.

When she meets Mogan through the online donor connect email, she immediately starts up by telling him she loves things that she finds out about him on his social media presence. Soon they are together, depict her family & friends' objections, but she soon stops trusting hr new husband as although she has his wife's heart, she wonders if his deceased wife died as an accident as she was told or if he had something to do with.

the book will suck you in from the first page and y0u will not be able to stop reading until you get to the end.

DAMN! This book transcended all other thrillers for me. And just when I thought that I figured out the twist and patted myself on the back, the author laughed and I realized, I KNOW NOTHING! At first, I was discomforted by Rosie's personality. She was definitely channeling the cringeness of Anna Kendrick's character in "A Simple Favor." But a much deeper plot is quickly reveal and totally sucked me in.

We follow Rosie who has just emailed her heart donor's husband on the anniversary of her transplant. She's had suspicions of his identity and confirms it as she reads between the lines of his replies. This book uses their "anonymous" emails to fill in the blanks as Rosie tells her story. But then he starts to email his friends about Rosie and I was obsessed reading them. It was a genius way to get inside his head instead of giving him POV chapters. When someone ends up dead and the police go through all of the messages, you start to see the discrepancies. It's brilliant!

I think Megan Collins has outdone herself and every comparable thriller. There's a rivalry element between literary spouses that reminded me of "Verity". But Rosie's protectiveness of her donor made it more palatable to me. So even as she's falling in love with her donor's husband, she has a sense of love for the woman who died and donated her heart. It's boldly feminine and feminist. The twist and shock factor felt as glorious as reading "Never Lie" by Freida McFadden but it happens much earlier in the story, so it was more satisfying. And the cat and mouse dynamic where Rosie knows everything about the husband before they've even met filled me with the same perverse excitement as watching the Netflix show "You." I will be sharing this with all my girlfriends and then debating which character we would be.

What begins as a heart transplant recipient’s simple desire to thank a donor’s family quickly spirals into an unsettling obsession.

I thoroughly enjoyed this clever psychological thriller. The premise is both original and compelling, with just the right amount of red herrings and twists to keep the tension high—especially in the first half, which propels the story through to a gripping conclusion. It was a fast-paced and entertaining read, and I’d definitely pick up more from this author. Highly recommended for mystery and thriller fans looking for a suspenseful ride!

There was something about this story that kept it from being totally compelling. Maybe it was Rosie’s compulsive behavior or maybe it was the multiple story lines that were hard to separate at times. The Morgan Thorne character was vindictive; Rosie was kind but desperate. Regardless the story was interesting and I had the killer wrong in the end and I am somewhat optimistic that Rosie will grow up and find her happy ever after.
