The book that I've read is The Whipping Boy.This book was written by Sid Fleischman and it was published by Greenwillow Books in 1986 April.
Prince Brat and Jemmy escaped from the castle
Prince Brat kidnaped by the bandits hoping to collect ransom from the prince
Jemmy pretended he was the prince to save Prince Brat
A bear saved the boys from the bandits while he was chasing them
The highwaymen pursued them through the tunnels
Jemmy convinces the bandits to head down a tunnel filled with rats, and once the bandits are attacked by the rats.
They returned to the castle.
The boys became friends at the end.
Message: I think the writer wants to tell us not to act like a frog under a well. We should always try to make our lives better. Just like Jemmy.
My favourite character: My favourite character was Jemmy because he was smart and he could solve problems staying in calm. When he saved Prince Brat ,he could make a plan very fast. That's the reason why he was my favourite character.
