When the adults of Brockton, Connecticut, morphed into gigantic, bloodthirsty monsters nine months ago, the students at Jefferson High barricaded themselves inside their school. Now eighteen-year-old Kay Kim is one of the Student Council members trying to keep her classmates from starving. Kay has no poker face and can't keep her mouth shut when she knows she's right, so when she accidentally learns a secret that threatens the delicate power balance at Jefferson, she's dragged out of the school in the dead of night and dumped in the middle of town in a secret assassination attempt. But when a raiding party of cheerleaders from crosstown rival Moore High comes to her rescue, Kay finds herself among ruthless, hard-partying road warriors who have adopted the feudal trappings of a once-popular video game. Life at Moore is violent and cliquish, but everyone is thriving. Everyone, that is, who survives the kingdom's periodic monster hunts. For Moore's beloved King Max demands only two absolute fealty and that everyone at Moore help kill the "dragons." If Kay wants to survive, she must be granted asylum at Moore–which means slaying dragons, not asking the wrong questions, and navigating the rival factions, love triangles, and political intrigues at court. But when Kay discovers a deadly secret that reaches all the way to Jefferson, her inability to hide the truth might spark the revolution that burns both schools to the ground.
