An epic and fast-paced tale of lycanthropy and female werewolf hunters…Every full moon, Iris kills werewolves. It’s what she’s good at. What she’s trained for. She’s never imagined doing anything else . . . until she falls in love with one. And being a professional werewolf hunter and dating a werewolf poses a serious conflict of interests. To add to her problems, a group of witches decides she is the chosen one – destined to save humanity from the wolves at the door – while her new boss, Blake, who just happens to be her ex-husband, is hell-bent on sabotaging her new reltionship. All Iris wants is to snuggle up with her alpha wolf and be left alone. He might turn into a monster once a month, but in a lot of ways Iris does too.
