Beauty and the Bastard — David Bridger

Saul the Bastard is a fallen angel who works as a bounty hunter for powerful urban demon families. Rebecca Drake, a modern day demon princess, is being hunted by dangerous desert demons. When Rebecca's family hires Saul to protect her, they are both unhappy with the arrangement, but before long sparks fly as they try to resist their strong mutual attraction. For the first time in living memory, Saul has someone to love; someone he is scared of losing; someone the desert demons have marked to be their next sacrifice.
