Travis and Corey are spending the summer at the grandmother's isolated Vermont inn--an excellent alternative to the summer camp they got banned from after last summer's pranks and mischief. Grandmother's inn isn't doing too well, though, since the ghostly activity has ceased, as people don't come so far out of their way to visit an un-haunted inn. The siblings vow to turn things around for their grandmother, and stage a haunting to convince the current guests that the inn still has some secrets. Their plan goes off the rails when the real ghosts awaken--from the mischief-making group of ghost children to Miss Ada's malevolent spirit. Since Corey and Travis awakened the ghosts, it's their job to put them to rest again--if Miss Ada's ghost doesn't put them to rest first. 
 This fast-paced ghost story will appeal to upper-elementary or early middle school readers looking for a quick thrill, but isn't fully developed enough to really hold an older reader's interest. The plot is predictable almost from the first page, and even the central characters never develop beyond their most basic attributes. Only the grandmother has any kind of change of heart, and her change from skeptic to believer is too abrupt--even under the circumstances--to feel at all authentic. The climax manages to be both sluggish and rushed, without any real sense of urgency. Still, this is a quick read to tingle the spines of kids looking for more gentle ghost stories, or for Hahn's established fans.
