Played out nicely.
Although the killer end up being an obvious choice it was hid well and misdirected to plausible people.
Enjoyed the story and the question posed at the end of is Rosie really changing or reverting back to old love habits?

I rated this two stars because I could have forced myself to finish it, but I just couldn’t. I absolutely love the premise, but the writing got to me. It was written in such a way that I felt like I was back to watching 1990s Lifetime teen movies; cue the Tori Spelling love and danger drama trope.

Rosie Lachlan wants nothing more than to find The One.

A year after she was dumped in her wedding dress, she’s working at her parents’ bridal salon, anxious for a happy ending that can’t come soon enough. After receiving a life-saving heart transplant, Rosie knows her health is precious and precarious. She suspects her heart donor is Daphne Thorne, the wife of local celebrity author Morgan Thorne, who she begins messaging via an anonymous service called DonorConnect, ostensibly to learn more about Daphne. But Rosie has a secret: She’s convinced that now that she has his wife’s heart, she and Morgan are meant to be together.

As she and Morgan correspond, the pretense of avoiding personal details soon disappears, even if Rosie’s keeping some cards close to her chest. But as she digs deeper into Morgan’s previous marriage, she discovers disturbing rumors about the man she’s falling for. Could Morgan have had something to do with his late wife’s death? And can Rosie’s heart sustain another break—or is she next?

Love it. Will recommend to others.

Love!!! At first I thought I wouldn't like Rosie, but as the story and characters progressed, I was pleasantly surprised. It's is such a captivating read! The structure of the book and how the different parts were woven together make the book very unique. Thank you, NetGalley.

This is a wild concept- a woman who received a heart transplant becoming fixated on the husband of her heart donor. I truly did not know which of the characters was most unhinged while reading this. Every time I turned the page, another twist was waiting.

This book has very long chapters and a lot of long email correspondence between the characters that got a bit tedious at times. Overall, a good storyline that is definitely worth the read!

Oh, hey! This book slays! I was so hooked I couldn’t put it down. What starts as a rom-com quickly flips the script into a jaw-dropping thriller. 😱

After a heart transplant, Rosie Lachlan suspects her donor was Daphne Thorne, wife of author Morgan Thorne. Through DonorConnect, she begins messaging Morgan, convinced her new heart has tied their fates together. But as their connection deepens, disturbing rumors about Daphne’s death make Rosie wonder if she’s in over her head—or in real danger.

This was such a unique thriller! Rosie’s slow descent into obsession keeps you constantly second-guessing everyone. With twists, red herrings, and unreliable narrators, it’s a total and complete rollercoaster. I especially loved the email and text exchanges sprinkled throughout—such a clever touch! A beautiful, fever-dream of a story that will keep you up all night. You NEED this book when it drops in January!

As if I couldn’t love Megan Collins anymore?! She writes this. This one had my head spinning and I thought I knew what was happening but I was so wrong. Any type of obsession trope always keeps me hooked.

I felt for Rosie and she also pissed me off. I wanted to take her “Rosie colored glasses” and run them over with my car LOL All the references to Swift and Friends were on point and so smart. We all know how the Swifies ban hee hee This was extremely entertaining and so much fun. I loved it. Thank you so much to @atriabooks and @netgalley for my advance copy! Add this to your list.

Rosie receives a life-saving heart transplant, and begins an email correspondence with the donor’s husband, a local author who lives in the same neighborhood. But Rosie soon believes they are meant for each other, and her obsession with the husband takes a turn when she discovers information that he may be responsible for his wife’s death. Cross My Heart turned out to be one wild ride, and to reveal too much of the plot would spoil the fun. This is a true page-turner as Rosie’s life spirals, and she doesn’t know who she can trust anymore. There’s plenty of “oh wow” moments, and the tension oozes from each page in this twisty thriller. Definitely a must read, highly recommended!, I received an ARC of this book from the publisher through NetGalley in exchange for an honest review.

Sometimes I find myself binge-reading from NetGalley and forgetting to do my reviews, then needing to go back and remember a book, but with this one, there was no need to push my brain for memories because I absolutely remembered this one! I read lots of thrillers and this one was really different and fast paced, but heart felt and also, the characters were drawn out perfectly. I’m a sucker for good characterization and good explanation of the atmosphere and this had both. The twists and turns were definitely awesome! Loved it!

Cross Your Heart by Megan Collins is Mad Woman by Taylor Swift (one of my very favorite TS songs) in book form. OH MY GOODNESS I absolutely devoured this book. I had so many theories, but I was still shocked by how some things played out. And the ending?!? Utterly brilliant! Obsessed. One of my top 3 thrillers of the year! Highly, highly recommend!

Rating: ⭐⭐⭐⭐
Genre: Mystery Thriller

Rosie Lachlan is a woman who receives a life-saving heart transplant. She is pleasantly surprised to learn that the donor's heart belonged to Daphne Thorne, the wife of renowned crime fiction author Morgan Thorne. As Rosie recovers, she feels an increasing pull towards Morgan, believing that a profound connection exists between them. Is this connection due to the heart of the wife she has received?

Rosie and Morgan start chatting on an anonymous online platform, and their conversations quickly turn into something deeper that makes it hard to tell what's real anymore. But as Rosie digs into Morgan's past, she stumbles upon some pretty unsettling rumors about Daphne's death. To avoid giving anything away about the mystery or the thriller parts, I will end my summary there.

This is my first experience reading a book by Megan Collins, and I must say it was a pleasant one. I initially thought the author was leading the story in a safe and predictable direction, but she surprised me by taking it in a completely unexpected direction.

The main characters are well-developed, and I found the use of different narration styles in this story to be not only effective but also crucial for building suspense. At certain points, the reader may begin to question the main character’s mental health, as this is a psychological thriller. If I were to offer a minor critique, it would be regarding the portrayal of several female characters who seem obsessed with a single man. At times, it felt like he must be the Don Juan of his time! LOL.

Overall, this was a very entertaining mystery and psychological thriller. The author did a great job with all its elements, keeping you guessing who is right and who is wrong until the end. I highly recommend it.

Many thanks to NetGalley and the publisher for providing me with the ARC of this book.

I really enjoyed this psychological thriller! Addictive, juicy and full of surprising twists. I flew through this one anxious to see what was coming next! Aesthetically, I love the cover. Solid ending! This was my first Megan Collins novel and I would definitely read another!

Thank you to the publisher and NetGalley for the review eARC!

I ended up DNFing this. The writing was fun at first but not sure how I felt about the numerous mentions of Taylor Swift and Friends. It got redundant when it was only 25% in and was mentioning both of this again. If you're big fans of that you'll be excited though! I also didn't enjoy the main character so I felt like it was hard for me to connect and want to continue.

this was a fantastic thriller. i can't say I knew where it was going at all and that's just my kind of mystery. i was jaw dropping, on my toes, head hurting in confusion. i can't say much without spoiling but definitely check this one out when it releases! Thank you to Netgalley and Atria for the ARC!

I’m giving this 4 stars because I enjoyed this thriller but I had a few frustrations as I read. For one, I could put this book down and not be drawn to it. Second, I got really tired of the women’s identities being found in their relationships with men. I get that was probably the point! Overall good twists and turns.
Thanks to NetGalley and Atria for an ARC in return for my honest review.

I loved Cross My Heart by Megan Collins! It was such a unique thriller premise that had me guessing until the last few pages.

After a heart transplant Rosie becomes obsessed with the husband of her donor.

I’ve read a lot of Megan Collins over the years and this was my favorite yet. There were so many twists and turns. It felt fresh and a new take on a thriller. I love how the story weaved in emails and texts making it multi-POV. I will be recommending this to everyone when it’s released in January 2025!

Thank you to NetGalley and Atria Books for an advanced copy of this book!

This fun, twisty story threw me for a loop. Ha! I enjoyed but at times was wondering “what the hell am I reading?”. It kept me on the edge of my seat needing to know why happened next and was an easy, fun read
For sure.

The first half of the story felt more thriller and then once everything came together it felt a little different but still Enjoyable. Not exactly what I expected but to be honest I don’t know what you could expect from
This story :) lol!

This book was a very different from the typical thrillers that have been coming out. Megan Collins characters were so unique and fleshed out.
The story follows Rosie a young woman that has recently received a heart transplant after hers was irrevocably broken. She was dumped by her boyfriend who she thought she would spend the rest of her life with and then she becomes truly sick.
She starts corresponding with the widower of the woman whose heart she received through the donor service. It is anonymous but she is positive that her heart comes from the local celebrity authors wife.
Their exchanges get more personal and Rosie begins to catch feelings.
From there things get crazy in a vey fun way.
I had a lot of fun with this book and it helped me get out of my reading slump.

I jumped on this one when I got an email about it because it seemed like a cool concept that was different. But ultimately it fell kinda flat for me. I think the first part was supposed to end in a twist but I just found it confusing. What had been real and what wasn’t? The majority of the characters are unlikable so it’s hard to root for any of them.

Thank you to NetGalley and the publisher for granting access to this book in exchange for my honest review.

Megan Collins has done it again!! She is back with another fantastic thriller. This is a thriller that could probably be considered for the list of best thrillers of 2025 (and yes I know it is early to say this, but just trust me). If you are looking for a fast paced thriller, I highly recommend this book.

Additionally, if you enjoy audiobooks, check out the audiobook narrated by Gail Shalan and Chris Andrew Ciulla,,,I definitely am planning to listen to this one...the book is just that good.

What a fantastic thriller... I can't recommend it enough!
