Death by Dragon by Madeleine Ribbon

Fell Harwick, half-incubus and witch extraordinaire, knows how he’ll die. Ever since he was a child, he’s had visions of a dragon tearing him to pieces. Since he’s not terribly fond of the idea–and the power-hungry vampire that killed his mother is now after him for his unprecedented healing abilities–he’s gone into hiding. But when a pair of shifters get shot in front of his cabin in the woods, he feels obligated to keep them safe.

Jett and Theodore are members of the local resistance, fighting against the same vamp that wants Fell. Theodore is a beautiful, tragic mess, and Jett hates all incubi on principle–something Fell finds out as he tries to take energy to power his healing magic.

Jett and Fell might have been able to work around one paranormal prejudice. Jett even encourages Fell into sex with Theodore when he needs energy. But then Fell discovers that his future killer has been sleeping on his couch.
