Cross My Heart: A Novel

From Megan Collins, a twisty and “terrific” (The New York Times) 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. The recipient of 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, 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?
