CHAPTER 1

Classroom 13’s Revenge

The 13th Classroom was not evil—it just didn’t like being left out of all the fun.

And the students of Classroom 13 were always having fun. Once, they won the lottery and didn’t give Classroom 13 any of their money. Another time, they found a magic genie djinn lamp and didn’t give Classroom 13 a wish. This other time, they all became super famous and the agent didn’t even notice Classroom 13 (…though it certainly showed her). Last month, everyone in Classroom 13 got superpowers—that is, everyone except Classroom 13. (Oh, and Jacob.)

The 13th Classroom was sick and tired of not being included. Now it wanted revenge! And for Halloween, it had just the revenge in mind.…

It left out a bowl of candy.

You might think that this was nice, but it was not. It was a nasty thing to do.

What’s that? You don’t believe me? You think candy on Halloween is nice? Just wait and see. Sometimes the best treats turn out to be tricks.
