The book was written by Maurice Sendak. He was born on June 10, 1928.
The hero of the story is a boy named Mickey. As he drifts off into the dreamworld of the Night Kitchen, he falls out of his pajamas and runs around naked. After a page or two, he dives into a bowl of cake batter, which sticks to him and creates a suit.
Sendak also wrote the classic children's story Where the Wild Things Are.
