An excellent start to an new urban fantasy series. The world building is really well done, and made me feel a part of the world without any sort of info dumping. I liked the characters both primary, and supporting. They were a diverse, and well developed group. I especially liked Kai. It was nice having such an openly sexual character without having sex become the primary focus of the story. I liked what I learned of his back story. It was dark, and while Kai is troubled he never felt whiny or self pitying. The plot was fast paced, and kept me on the edge of my seat. Once I started I really didn't want to stop. I am really looking forward to reading more in this series. I need to know where things go from here.
