After the worst Halloween ever, Carly Beth assumed that nothing could be scarier than a drooling rubber mask with a mind of its own. The Haunted Mask is its name. Don't wear it out.

One year later, the ugly, green mask mysteriously calls out to her again, and ugly, green masks don't like to be ignored.

If Carly Beth can survive the night, even a terrifying amusement park like HorrorLand might seem like a vacation. Then again, maybe not . . .
