The book "The Trouble Starts at 8" was a very good book written by Mark Twain ,who told the story of his life growing up and what he went through to become known as the person we know him as today.  Before I go into big details about the story.  The title "The Trouble Starts at 8" is not talking about Mark Twain getting in trouble at 8 years old.  It's towards the end of the book his story he tells in theaters was called "The Trouble Starts at 8."  This made him famous.  He told thousands upon thousands of people but all before this he was poor, and started to learn the Mississippi River, turn by turn, by heart.  And the money that he made, he used to move and start his career of literature.  After all his struggles at the end of the book, he became the legendary writer Mark Twain.
