Curse of the Moon (Dark Moon, 2) by Marie Medina

English Edition

Gerard was destined by blood to become a vampire, but chose to become a werewolf in an effort to escape the sadistic vampire clans. When Morgaine, the queen of the vampires, tricked him into drinking her blood, he was burdened with the powers of both races. He thought he was rid of Morgaine after their final battle but now, after a year of peace, she’s invaded his life again. Her actions draw the attention of a vampire hunter named Chris, whom she soon entangles in her schemes. She tries to separate Gerard and Chris and changes the rules of the game every time she makes a move. Both men find it increasingly difficult to work together and protect those they love as Morgaine draws out her seductive games in an effort to possess both of them.
