Persephone “Fen” Fenwick is a legacy slayer whose work has run a little dry since the Master Vampires began governing their own. But after a transfer to Vancouver puts her life in danger, she realizes there is only one person she can trust: a man she’s never met, who isn’t even a man. He’s a vampire. And a Master Vampire at that. Sparks fly when Marcus Vine meets his match, and the two of them have to work together to find out who has put a target on Fen’s back, all while trying to douse—or maybe even stoke—the heat between them.
