Finders Keepers — Jeff Strand

A scavenger hunt takes a sinister turn in the third novel in the Eek! series, tales to scare you silly!

In the small town of Farlow, mysterious advertisements appear for a summer scavenger hunt. Twelve-year-old Maggie and her friends can't wait. They have their team, and more than bragging rights, they want that huge cash prize.

On the big day, a strange man welcomes everybody to the game. The first items are ridiculously easy ("An egg? Seriously?"), but they quickly grow more difficult. When getting one of the items requires an actual crime -- breaking into the school after dark -- Maggie loses one of her teammates. But the others manage to steal Mr. Kramer's favorite mug.

A bone from the cemetery seems like it's as dark as the game can get, but when they're asked to bring back a human head, nobody wants to play anymore. But it's too late to quit…
