Nikki James in in San Francisco at the request of her business partner and friend Jake. His friend's wife is missing, when they hunt the kidnappers they find vampires and a dead body. Michael Kelly has returned from a vampire hunting expedition in Ireland. He is reluctant to get involved in Nikki's chase, he wants her to stay away from the evil and from his world of darkness. However he can't stop Nikki from doing what she must. It's an interesting read, the characters are quite interesting and their motivations are fairly believable. I like too how the characters don't get it easy with love, it both makes things easier and harder for them.
