This is a wonderful book! It brings a lot of imagination to a lot of kids. From this book I learned the population of Nebraska quite well! Because I think the author is obsessed with the population of Nebraska, which is 2 million and seven. I liked the story because the Facttracker had a bunch of arguments with the evil Lies in the Liebrary, and Eratze was really evil. I liked how the just small enough boy became the Facttracker at the end. And the old Facttracker went off to Mexico to teach the Mexican hat dance. I recommend this book to all kid readers. It's wonder
