Oliver's having trouble getting to sleep. Why? It's not as if he's afraid of the dark, or ghosts, or something hiding under the bed. The problem is that every night Oliver is bothered by the wildest, rowdiest, worst-behaved monsters anyone has ever met -- and they won't leave him alone! Then comes the moment when Oliver just can't stand it anymore. So he sets off for the house where the monsters live to see if they enjoy being awakened by a small boy. Rarely have we seen a book that better captures a common childhood fear and deals with it in a humorous and effective way. Beautifully illustrated, humorously written -- every child deserves to read this book.
