Moonlight

Lucas is the leader of the Dark Guardians, a pack of werewolves that meet deep in the heart of a state park whose existence is threatened by a sinister bio-tech company. Rheena is a normal seventeen-year-old who loves camping and the outdoors; but she's adopted and has no idea that she's inherited the gene that will turn her into a wolf.

Rheena can't understand why she's so drawn to distant, aloof Lucas-until it's almost too late to save him.
