Aspiring special effects wizard Desmond Pucket carries his pranks too far, putting his field trip to Mountain Full of Monsters at Crab Shell Pier in jeopardy.

Twelve-year-old Tulah Jones has problems; her best friend is upset because she thinks Tulah is hiding a secret (true), and she is playing the lead female part in the school musical, and will soon be sharing her first-ever stage kiss with Jeremy Romero, the boy she has a serious crush on--trouble is that the secret she is hiding is that some weird virus has turned her into a zombie.

The first mistake twelve-year-old Tulah made was allowing her best friend, Nikki, to dare her into auditioning for the school musical, the second mistake she made was eating the Friday mystery lunch in the school cafeteria; now she finds herself turning into a zombie, with a craving for raw meat, and a body that feels stiff and awkward--but she still has to go through the audition on Thursday, and stage fright will be the least of her problems.
