"When Ben Harp sees his teacher's watch crawling across the hallway, he thinks he must be dreaming.

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".
