Three

During the full moon, the vampires gather to renew their bonds. It takes three, and those in groups have total power over those who aren't. For Luc, alone since he was created, the full moon is his only opportunity. Seeking blood to satiate him for the month ahead, Luc finds a rival instead: Anders, a demon just as alone, who's also on the hunt. They choose the same prey: Curtis, a handsome young man resistant to their supernatural charms.
When neither a vampire's glamour nor demon's passion work on him, it becomes clear their only chance of success lies in the unthinkable: working together.
