"It started last week. Though I guess it would make more sense to say it started next week. . . ." So begins "Yesterday Tomorrow," in which time moves backward before moving forward again-in a most unpleasant way. In other stories in this collection, an umbrella eats a boy, a girl casts a spell on herself and can't stop talking, and two boys battle it out to see who can eat the hottest pepper. Thirty-five original "warped and creepy" tales range from scary to weird to disgusting to silly. Author notes on story ideas and origins.
