Cat is a self styled vampire killer. And half vampire herself. She is doing pretty well on her own. Then she meets Bones, a vampire, who is a bounty hunter who also kills vampires. He forces her to team up with him. And they both find forces at work that are bigger than they expected. 
 I like Cat. She is young, brass and determined. But motivated by hate until she learns that all vampires are not the same. 
 The book was good. I wanted to smack the Sh#$ out of her mother though. A woman who was hurt badly who cannot get over her pain and hate and projects so much of it on Cat. 
 I also liked the setup for the series with Cat's future vamp hunting career. What I did not like was the choice she made re love. I'll have to see how it plays out in the rest of the series
