As long-suffering Peter knows only too well, being a big brother is sometimes nothing but a big pain. Emily, his baby sister, has been a nuisance all her young life, but she has simply gone too far! By throwing his new baseball cap into the toilet, Emily has disregarded all the rules of fair play. Now, as far as Peter is concerned, there is only one solution. He must find her a new home! What follows is a series of misadventures and spirited hi-jinx -- playfully captured in expressive pen-and-ink and watercolor illustrations -- that will have young readers laughing out loud.
