Scholastic Waking nightmare (hello neighbor, book 2), paperback/carly anne west

It's been a month since Nicky Roth received a note from his best friend, Aaron Peterson.

A month since that note went missing, in its place, a bloody handprint.

And a month since Aaron and his little sister disappeared.

Could Mr.

Peterson, the theme park designer, be the one behind the kids' disappearance, or is Nicky knocking on the wrong door?.
