The seven most popular boys at Decelis Academy all share a secret -- they're vampires. Keeping their identities concealed and dealing with their werewolf rivals is trouble enough, but the appearance of a mysterious new student only further complicates things. The girl, Sooha, also has hidden powers, and the boys can't help but feel an inexplicable attraction to her. As Sooha and the vampires find themselves increasingly drawn toward each other, murky pasts and intertwined futures threaten to turn their world upside down. Just what fate awaits them under the dark moon...?
