Revenge. It's all Grayson Spencer wants. Christophe dit Menart, a human with dark magical powers, destroyed the life she loved. She wants the pleasure of killing him, no matter the cost to her. If not for Durian, a dangerously sexy demon fiend charged with keeping Christophe alive, she would have succeeded, too. Now, she's certain all hope is gone. But he has a plan and an offer she can't resist...

Durian has spent his life as a trained and sanctioned assassin. His duty: to enforce the laws against demons harming humans. He's always prided himself on staying out of the fray, carrying out his orders and honoring his fealty to his warlord, but never getting attached. Never until Grayson, a spunky and determined woman clearly gifted with magic herself. He convinces her to swear fealty to him so he can protect her and teach her to use her magic to taste the revenge she so desperately wants.

They're soon bound together in a forbidden desire--a dangerous passion that calls into question Durian's oath of loyalty to his warlord. When he refuses to return her to Christophe, his disobedience threatens to inflame the tumultuous war between demons and the magekind. Can they--and their love--survive?
