Fright-master R.L. Stine invites you on an all-new, all-terrifying
adventure! When Matt ordered a container of Monster Blood from a
weird website, his only intention was to play a harmless practical
joke. But the joke's on him--and so is the mysterious green ooze.
He's even eaten some of it! As if Matt's problems weren't big and
slimy enough, an invitation to HorrorLand is also on its way. Can
Matt and his sister survive inside a terrifying scream park where
trouble lurks behind every turnstile? Can YOU?
