A hilarious look at what happens when boys and monsters mix... When a little boy receives a letter from a monster, inviting himself over to play, the boy isn't quite sure what to do. Afraid to offend, manners in hand, the little boy invites the monster over for Saturday. Strangely enough, it seems the monster is facing a similar crisis of etiquette — his letter was meant for his monster cousin, who just happens to live underneath the boy's bed! Told in funny rhyming verse, with striking black-and-white illustrations and spot colour, this story is sure to keep kids howling.
