Under normal circumstances, a Time Fetch sends out its foragers to collect only those moments that will never be missed or regretted. It then rests, waiting to be called back by the Keeper, who distributes the gathered time where it is needed in our world and others. When eighth grader Edward innocently mistakes a sleeping Fetch for an ordinary rock, he wakes its foragers too early, and they begin to multiply and gobble up too much time. Soon the bell rings to end class just as it's begun. Buses race down streets, too far behind schedule to stop for passengers. Buildings and sidewalks begin to disappear as the whole fabric of the universe starts to unravel.
