For more books of this sort, try Angie Sage's [[Ghostsitters by Angie Sage|Ghostsitters}}. It's often hilariously funny. More of a girl-book, though. Boys will prefer [[The First Escape (Dopple Ganger Chronicles) by G P Taylor|The Doppelganger Chronicles: The First Escape]] by G P Taylor, an action-packed mixed-media offering that's not as funny but quite as silly. Or if you're looking for something seriously scary, read one of Chris Priestley's [[:Category:Chris Priestley|Tales of Terror]]. I loved the first two, and Bookbag loved the third and newest (which I haven't read yet but am positively dying to), so have at 'em!
