The Scream of the Haunted Mask - R L Stine

It's a whole new ride from master of fright and bestselling author R.L. Stine--with a story so fiendish that it can't be contained in just one book!
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 . . .
