Monsters — Stewart O'Nan

They were going to be monsters, for the church; Creatures from the Black Lagoon. Mark and his best friend Derek would each get to wear a suit with a zipper up the back and a head that fit like a diving helmet. They could scare the little kids and gross out the girls. No one would know who they were.

A backyard accident ensures this Halloween will be even more memorable than the young boys expect. Their friendship will never be the same!
