The Zombie Stone (Zombie Problems, Bk.2)

August DuPont has a small problem. When a zombie followed him home one day, he didn't expect her to stick around. But his very dead great-great-aunt Claudette is in no hurry to leave August's side. In order to rid himself of his clammy sidekick, August must hunt down the elusive Zombie Stone. His frantic search leads him through a bizarre carnival and back to his dour cousins, the Malveaus. Throw in a necromancer, a pop star with attitude, some armadillo people, and four new zombies (that's right, four!), and you'd better believe that August's small zombie problem is only going to get bigger.
