She has his wife’s heart; the one she wants is his. 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.
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?
Don’t just take
our word for it
"[S]pine-tingling… Collins expertly homes in on her characters’ complexities, nailing the way Rosie’s vulnerability gradually slips into obsession. With a pulse-pounding finale and plenty of exciting plot twists along the way, this is difficult to put down."
- Publishers Weekly
"If Nora Ephron had written your favorite thriller, it would be Cross My Heart. Equal parts spine-tingling and soul-wrenching, Collins’ latest unpacks the perils of parasocial relationships and the lies we tell ourselves with devilish wit, sizzling prose and a hair-raiser of a plot. The twists will have your jaw on the floor and your heart beating in time to Rosie’s borrowed one. A true pulse-pounder with one question at its core: how far would you go to be with the one you (think you) love?"
- Leah Konen, author of The Last Room on the Left
"With her fifth novel, Megan Collins proves once again why she should be on everyone’s must-read list! Cross Your Heart is the best type of psychological suspense–one that you want to immediately read again once you get to the last satisfying page. It has everything I love as a reader – an unreliable yet sympathetic narrator, cast of deliciously twisted people, razor sharp observations about relationships, and one twist after another. I read it in one night!"
- Kellye Garrett, award winning author of Missing White Woman
