Hide And Shriek — Melissa J. Morgan

Have you seen Cropsy?
He's the madman hermit who lives in the broken-down shack just outside Camp Lakeview grounds. Every six years, he emerges to seek revenge for the arm he lost while trying to end a camper's life.

This is year number six.

Are you afraid? Don't be. The legend of Cropsy is just a spooky story told for fun.

At least that's what the girls of 5A think…until Chelsea vanishes.
