Stine, R. L. Nightmare room #10

You hold in your hand the key to a shadow world of shivers and screams. Take a step away from the safe, comfortable world you know. Unlock the door to terror. There's always room for one more in... The Nightmare Room. Mr. Moon is throwing a Halloween party, and Tristan and his best friend Rosa have been invited. How lame! Tristan thinks. He'd rather be trick-or-treating than hanging out with his teacher! But Mr. Moon's party is far from lame... because he's got a couple of werewolves on the guest list! Can Tristan escape the party? Or will he find himself trapped by a werewolf in The Nightmare Room?
