From Megan Collins, a twisty and terrific (The New York Times) novel about a heart transplant patient who becomes romantically obsessed with her donors husband.
She has his wifes 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, shes working at her parents bridal salon, anxious for a happy ending that cant 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: Shes convinced that now that she has his wifes 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 Morgans previous marriage, she discovers disturbing rumors about the man shes falling for. Could Morgan have had something to do with his late wifes death And can Rosies heart sustain another breakor is she next
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
[S]pine-tingling Collins expertly homes in on her characters complexities, nailing the way Rosies 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
Collins, who specializes in fiendishly clever psychological thrillers (including The Family Plot, 2021) outdoes herself here with a jaw-dropping premise that tightens into a deadly cat-and-mouse game Collins keeps the suspense at cauldron-bubbling intensity throughout. A bravura performance.
