Rosie had to have a heart transplant and her donor was the wife of a famous author, Morgan. They begin to email each other through DonorConnect although they don’t use their names. Rosie figures out who is his and begins digging into his life and why his wife died. This book is a solid thriller but it’s also the story about how we act when love doesn’t live up to our expectation.

4.5 stars

This is for every woman who has ever been called "crazy" by an ex! And it was sooo good!

Rosie Lachlan keeps hearing that she's "too much" from her boyfriends, but all she wants is to find The One. After receiving a heart transplant, she believes she's found that with Morgan, the husband of the heart donor. But was his wife's death really an accident?

I absolutely loved the characters in this. Rosie is an unreliable narrator, can easily come off as unhinged, but I just liked her SO much. And her relationships are so charming but all have just enough of a hint of suspicion, so you really can't trust anyone. I did guess one big twist, but I didn't have it completely right and it was so completely engrossing I couldn't put it down.

And the ending was just so completely perfect

@megancollinswriter is quickly becoming an auto-buy for me, definitely check this one out!

This was my first book by Megan Collins and IT. DID. NOT. DISAPPOINT. I love the whole premise behind this book. She has his late wife's heart, are they destined to be together?? I predicted part of the "twist" early on...However, the ending twist was not 100% what I predicted. I loved this book, I enjoyed the character development on all of the characters, and honestly solid plot twist. Definitely would recommend.

Obsession, murder... creepy stalker vibes... the perfect kinda book. I can't love this more. The suspense just kept getting more intense. Definitely a 5 star read.

Megan Collins' "Cross My Heart" is an emotionally charged contemporary thriller that will keep readers on the edge of their seats.

The story centers around Rosie Lachlan, a heart transplant recipient who becomes obsessed with - and romantically pursues - her donor's husband, Morgan Thorne. This twisty tale of obsession and suspense is a rollercoaster ride from start to finish.

Collins' pacing is masterful, balancing moments of high tension with quieter, introspective scenes that delve into Rosie's psyche. The characterization is spot-on, with Rosie emerging as a deeply flawed yet sympathetic protagonist. Her journey from heartbreak to obsession is portrayed with nuance and empathy, making her a compelling character to follow.

The supporting cast, including the enigmatic Morgan and the mysterious Daphne, adds layers of intrigue to the story. Collins skillfully weaves their backstories into the narrative, keeping readers guessing about their true motives and secrets.

"Cross My Heart" is gripping, well-plotted, and features well-drawn characters. The novel's exploration of themes such as love, obsession, and the fragility of life is both thought-provoking and entertaining. With Collins' signature sharp and engaging prose, this a standout psychological thriller that is sure to be a hit with fans of the genre.

The leaves had started falling from the trees, their nearly bare branches were menacing as she walked through the wooded area. The dry leaves crunched beneath her feet and she picked up her pace as she came closer to the house she liked to admire. Her heart rate picked up in anticipation, a heart that beat stronger than she thought possible.

Cross My Heart is a thriller following Rosie, the recent recipient of a heart transplant. Working in her parent’s bridal boutique, she is surrounded by happily ever afters, but hasn’t found her own. When she strikes up a conversation with the widower of her heart donor… she begins to think that she may have found her person.

This book was unhinged in the best way. Definitely a thriller that will keep you engaged and questioning a lot of things. I wasn’t a fan of the overly long chapters, but this read was twisty and suspenseful!

If you like psychological thrillers with obsession, unreliable narrators, and unhinged characters… add this to your 2025 release purchases!

Rosie works at a bridal shop and has had more than her share of heartbreak. Her path to recovery from a heart transplant surgery was slow but her physical and emotional wounds are slowly knitting together. She realizes how fortunate she is to have a second chance so extends grace to others. She and the heart donor's husband begin corresponding and discover more about each other's lives. But things take twisty turns and all is not as it seems. Who can Rosie truly trust?

I really liked this thriller. Sometimes circumstances aren't convincingly believable but its originality and cleverness win points. Easily. It isn't nail bitingly tense but it is suspenseful with brilliant surprises. When author characters are involved, I hope for beautiful prose and turn of phrase. This scratched that itch. Those with health issues like myself will surely relate to Rosie's feelings and caution.

I had been seeing so many reviews for this one so I just had to accept the widget. It is a fast paced thriller that will have you turning pages. It is definitely one I'll be recommending to get out of slumps.

Our story starts with Rosie, who is just getting back on her feet after a heart transplant. We are led to believe that prior to Rosie’s transplant that she was left by her fiancé on the day of her wedding, however we later learn that Rosie’s viewpoint doesn’t always match e stone else’s. Through a website, Rosie is able to connect with the family members of her donor. But when Rosie starts to have feelings for the husband of her donor, the people closest to her start to become concerned. Rosie learned her donor was the wife as local author. As she begins “researching” more about him, she begins to question the death of his wife and their relationship in general. But nothing can prepare Rosie or heart for the next twist in her story…

This book was my most difficult read of 2024. The first half of the book took me forever to get through but I flew through the second half. My biggest hang up with the book was the unlikable main character, Rosie. Rosie is characterized as a woman with unhealthy attachments to the men with whom she has relationships. She has exaggerated reactions to rejection. These depictions are harmful to women. After reading the second half of the book, I realized that was purposeful in order to show what can happen when women are not respected and used in relationships. On the flip side, it’s a warning to women to not ignore red flags and respect themselves.

Thank you to the publisher, author, and NetGalley for this ARC in exchange for an honest review.

This is going to be a top 2025 thriller!!! A year after receiving a heart transplant Rosie reaches out to the donor’s family via an anonymous connection service for organ recipients and donors. The donor’s husband replies and they start communicating, each interested in finding about the other.

It’s best to go into this book blind so I won’t tell anymore about the plot but this is a book every thriller lover needs to read. The characters are so real and the plot is extremely well done. The book had me refusing to put it down and questing everything. I’m so glad I read this book!

A deep dive into the psyche of the main character as she navigates emotions and the aftermath of a heart transplant as well as a painful break up.

What a great read! There were so many twists and turns! Just when I thought I had it figured out, I was completely thrown off!! What a crazy ride!

Thank you NetGalley for the advanced reader’s copy!

Thank you NetGalley for the e-arc of this book! 4.5 stars! I wasn't sure what to expect going into this one, but it had me gripped from the beginning. There was a plot twist halfway through, and I thought I knew where it was going after that, yet it took different turns and still continued to surprise me. This was a fast-paced thriller that I really enjoyed!

This was a super entertaining and quick thriller that had me interested from the beginning.

Rosie is a woman with an obsessive behavior, who decides to connect with the husband of her heart transplant donor. This initial interaction leads to a whole series of events. I can’t even share more than that because it would reveal spoilers.

I appreciated that there was no build-up in this thriller. Even though the plot itself wasn’t inherently fast-paced, the fact that there weren’t filler plot points made it seem quicker. The plot twists were fun at first, but quickly became too far-fetched to be believable. I also found myself frustrated with Rosie. It felt like watching one of those horror movies where you want to step into the story and shake the main character for continuing to make poor decisions.

Overall, still a fun read and I don’t regret picking this up. Thank you to NetGalley and Atria Books for the ARC in exchange for my honest review!

This is my first time reading a book by this author. With that being said, let me review this book. Rosie was left at the alter. She only wants to find someone to love. Working in the bridal salon also adds some heartache. Plus she needs a heart transplant which she gets. Through donor connect she figures out who her heart is from. Daphne Thorne, married to Morgan Thorne a novelist. She really wants to meet him but there are rumors that Morgan killed his wife. The first half was good. The second half was okay. There is a major twist in this book. I received this book from net galley and the publisher as an ARC for an honest review. I gave it three stars because it was a little to long but it was a decent read.

This was a wild ride from start to finish with a complex FMC. Poor Rosie not only needed a heart transplant, but she was dumped while wearing her wedding dress. Her search for love and who donated to heart takes her on a plot twisted rollercoaster of a ride. Totally enjoyed this book!

Thanks for the opportunity to read!

Rosie just wants to be loved. Her last relationship left her with a broken heart, so broken in fact that she needed a heart transplant. When she starts talking with the donors husband through an anonymous donor site, she also suspects out that she is talking to the famous author Morgan Thorne. The more she learns about his wife and her death though, the more she questions if it was really an accident.

PHEW this book had lots of turns. Honestly, I truly hate to say this word the talking about women, but since these women were fictional….we were dealing with some crazy ladies in this one! Not that there weren’t men that made them that way, and I hated them too, but several of these characters needed some serious therapy! I could feel how desperate Rosie was to feel loved, and I just wanted to jump through the pages and be like girl…you don’t need a man! I did not see the story unfolding the way they did and fully enjoyed this ride!

Thank you to @atriabooks for my gifted copy of this book!

Wow… this book had me so hooked I read it in a day! This was a wild ride I did NOT want to get off. I didn’t know whether to sympathize with Rosie or to try to talk some sense into her, but I’ve settled on a little bit of both. I love a thriller that misdirects the reader and this one accomplished that without a doubt! My conclusion is that the only thing Rosie needs more than love is some serious therapy….

Thank you to NetGalley and the publisher for the copy. Cross my Heart follows Rosie, a bridal shop manager, as she connects with the family of her heart donor. It is supposed to be an anonymous service but Rosie knows who she is messaging. It is Morgan Thorne, a famous author. Rosie develops a crush, and this starts a chain reaction. I enjoyed all of the references to Friends and Taylor Swift. I thought I knew where this was going, and there was a little twist. I do feel like maybe the story was little rushed. It did have similar vibes to You.

received a complimentary copy of this novel from the puublisher. All opinions expressed in this review are completely my own.

To be completely honest, I wanted to like this novel more than I did. I connected with Rosie, and liked that she befriended everyone she met. However, I felt that the story became too far-fetched and found myself getting annoyed that no one believed her. I kept reading because I wanted to find out what happened and why, but by the end I did not really care. I was surprised by the twists and turns that the story took, but did not find them shocking.
