Query: BoBBy BaseBall

Bobby Baseball is an incredible book. Its about a boy who loves baseball so much he calls himself Bobby Baseball. Bobby wants to become a major league pitcher, but he has to start at his own Mustang league. The middle of the book is very good and it makes it so you won't want to stop reading. The ending is very strange and you will need to make up your own opinion if its good or not!Harry age 10
