Love is a dangerous game when your clients are killers…from the bestselling author behind Love Letters to a Serial Killer.

When Lexie's fiancé runs off with her so-called best friend on her birthday, her carefully crafted fairy-tale life shatters. Having survived horrors in her past, she was determined to finally get her happily-ever-after—and she's not giving up yet.

To distract herself, Lexie throws herself into her unusual job: matchmaking psychopaths (a specialty her clients are blissfully unaware of). But the loneliness is crushing. So when a gorgeous, overprotective new client named Aidan insists they're soulmates, and another intriguing client, Rebecca, seems perfect to fill the best-friend-shaped hole in her life, Lexie can't help but find the attention comforting—despite her own professional boundaries.

Then a human heart appears on Lexie's doorstep. As more threatening packages arrive and her fiancé mysteriously disappears, she must confront a terrifying question: did she inadvertently match herself with a killer? Between Aidan's claims that her fiancé will never return, Rebecca's growing presence in her life, and her own dark past resurfacing, Lexie's matchmaker instincts are being tested like never before.

Because someone is determined to ensure her story ends with a funeral.
