Mercy Thompson is a mechanic and a shapeshifter. Her friends include Fae, Werewolves and a vampire. She keeps a low profile as best she can until a new werewolf in trouble shows up on her doorstep and things go very wrong. 
 I loved this book. Brigg's world building skills are excellent. The characters are engrossing and the dynamics between the werewolves particularly intriguing. I will definitely continue with this series.
