Cross My Heart: A Novel

“Part (possible) murder mystery, part deep dive into out-of-control social media addiction, and part sleight-of-hand trick by the author...terrific.” —The New York Times

The author of The Family Plot brings her signature “taut, emotionally charged, and propulsive” (Jeneva Rose, New York Times bestselling author) prose to a twisty novel about a heart transplant patient who becomes romantically obsessed with her donor’s husband.

She has his wife’s heart; the one she wants is his.

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?

For fans of “You” this one is deff twisty and bingeable. The FMC is an unreliable narrator and the plot kind of gets flipped on the second part but I enjoyed this one alot. It was fun and kept me on my toes.

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!! ❤️
