Danny and his friends are officially seniors of Casper High. A month away from graduation and suddenly Danny is sick of Amity Park's ignorance. Refusing to play innocent any longer- and hoping everyone will finally get a clue- the golden trio of Amity Park lets loose. This town is in for a wild month.

No one but Danny was suspicious when his English class was awarded an all-expenses paid cruise trip by an anonymous benefactor. Everyone but Danny thought it was bad luck when they became ship-wrecked on an island in the middle of nowhere. No one but Danny fully understood the dangers lurking in the trees. No one but Danny knew how much danger they were all in so far from home.

When Danny's transformation is caught on tape, Danny has a whole new battle to face, including a press conference, Valerie, and, of course, school. But who is the mysterious ghost who set him up? And how much can he possibly mess up his life?
