With the Hidden government in shambles and a string of deadly clues to follow, Zoey and her reaper boyfriend set out on a cross-country chase to stop the kidnapper from killing the captured Aegises. Along the way, they pick up a miniature golem who's on a quest to find his humanity and may be the key to solving the grisly clues.
