Full Moon Halloween

Full Moon Halloween is the 10th book in The Nightmare Room series.

Synopsis
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?
