This book is the first book of an on going series. The main character is Mercedes "Mercy" Thompson who is a VW mechanic living in the Tri-Cities area of Washington. Her Native American lineage has gifted her with the ability to shift into a Coyote at will and is known as a "Walker" to the mystical community of werewolves, vampires, and fey. This book is well written and does not overwhelm the reader with explicit details of Mercy's romantic relationships like so many other fantasy books often do. Highly recommended for a fun and enjoyable read!
