Twelfth Grade Kills (The Chronicles of Vladimir Tod #5) - by Heather Brewer

It looks bad for Vlad. The Elysian Council has decided that Vlad must die in a matter of weeks. At the same time, the Slayer Society aims to kill him, or, if they cannot kill him, they will kill the entire citizenry of Bathory. A bloodbath is inevitable. Vlad can fulfill the prophecy of the Pravis but he does not know who he can trust. Those on whom he thought he could rely are no longer loyal to him. His judgment will be tested as he tries to make it to high school graduation!
