There is a boy under Bobo's bed. A scary boy with pink skin and orange fur on top of his head, and, worst of all, eyes the awful colour the sky is when you wake up in the middle of day. So next bedtime, Bobo crawls under the kitchen cabinet and decides he's not going to bed, not now, not ever. But then Boo-Dad comes. And Boo-Dad, the biggest, baddest grandpa ever, has the answer to Bobo's problem, if only Bobo can be brave enough to give it a try. Very soon in the story you realize that things are not quite the way you thought they were; and that who is who's monster is open to question.
