Query: Not a very good book

Not that I expect much from books like this but come on, even I (a 15 year old boy) could write a better book than this. Here's an idea: Kids get lottery ticket, find out it's a winner and chase it all over town loooking for it. So original. Not a very good way to spend 30 minutes...plus you can predict the entire book just by reading the titles of the Chapters in the Table of Contents. Skip this one.
