Ivy Cole And the Moon

Ivy Cole is a vigilante werewolf who uses her monthly change to rid her town of people who she thinks deserve to die. She's lived the life of a lone wolf who has to move on whenever her neighbours get a bit suspicious but in her new home she is trying to put down roots. She's making friends. She's dating a local deputy. But her extracurricular activities are bringing some unwanted attention as the local law enforcement are out to catch whomever or whatever is killing community members and keeping everyone scared. And to complicate matters there is another werewolf in town and he doesn't share Ivy's code and Ivy is on his radar as well.

This is a really excellent urban fantasy by an author who has unfortunately only written this one and a sequel Luna. This book has benefited by the author's extensive research into wolves.
