Zachariah Thomson has spent the past year getting used to the idea that his best friend, Charlie, and the lovely Luna are now vampires-just like him. As they all learn to cope with the changes this strange new state of affairs brings, a mysterious creature appears. Likened to the Beast of the Apocalypse, it begins to dismantle the network of support around zack, who discovers he is the subject of an ancient prophecy that relates to the End of Days. As friends and enemies, old and new, throw his world into chaos, zack is forced to re-examine what it means to be good at a time when it seems that only the strong and the ruthless can survive.
