Iron Kissed (Patricia Briggs)

Another story of Mercy Thompson, the shapeshifting mechanic and her world of werewolves, vampires, witches, and fae. She is called in to investigate a series of murders in the fae reservation: murders that have never been reported to authorities because the fae handle these things themselves, but Mercy's fae friend Zee thinks her special coyote abilities might be useful. Along the way Zee winds up imprisoned for a murder he didn't commit and Mercy finds herself a target of the real murdered, who stalks her for his own twisted pleasures. Mercy's ties to Adam, the Alpha of the local werewolf pack, grow ever tighter in this story. I'm really loving these books!
