Whole book. This is a take off from the classic the Prince and the Pauper.
Prince Horance is a really bad spoiled prince. They call him Prince Brat. He is not allowed to get spankings when he does things that are wrong. So an orphan boy named Jemmy is taken from the streets to be whipped for him.
Prince Horance runs away and takes Jemmy with him. The boys have a wild adventure and get caught by two thieving cutthroats. Jemmy has to use his knowledge of the streets to get them out of all kinds of predicaments. Prince Brat is so spoiled that he doesn't even have common sense. He learns a lot about his kingdom and subjects. He learns what friendship and loyalty really mean. He has some very valuable life experiences on the streets and I hope he is at better king because of it someday!
