Widdershins

Grey witch Emma Harlow is no stranger to the monsters that hunt the night. She's lived her life on a razor's edge between Good and Evil, always managing to stay this side of the shadows. Barely. But when an unstoppable beast targets her for death, the hunter becomes the hunted. Forsaken by her coven, Emma turns to the only ally she has left with a dangerous proposal he won't be able to resist. Caszel Be'Phar, demon warrior of the Fesha Order, has no patience for wics who play with dark magick, then cry foul when that darkness bites back.
But there's something different about Emma, and it's not just the payment she offers for his services. Every touch, every kiss, casts a spell and, for the first time, Caszel is confronted with a force he cannot fight. The deal is struck. The trap baited. And as their enemies draw closer, so do Emma and Caszel. Before this battle is over, they'll discover the only thing more dangerous than the creature that wants Emma dead is the flames that ignite whenever they touch.
and someone is going to get burned.
