Attack of the Jack-O-Lanterns, by R.L. Stine

There's a boy named Drew.  Usually he and his friends love Halloween.  But the last two Halloweens were ruined by two people.  So this year Drew and his friends are planning to scare the two people but things go very wrong.

I liked this book because weird things happened.

Two other books I would recommend are:

Princess Academy: The Forgotten Sisters AND Wonder
