When Ben Harp sees his teacher's watch crawling across the hallway, he thinks he must be dreaming. But no, he's just seen his first Sneak--an interdimensional mischief-maker that can borrow the form of any ordinary object. He figured this school year would be bad... and he's stuck doing a group project with two similarly friendless girls, Charlotte and Akemi... Now Ben, Charlotte, and Akemi are trying to understand a book that seems to contain a coded map while being pursued by violent clothes hangers, fire-spitting squirrels, and more.
