Query: A great children's book! Great for all ages!

I loved this book! My favorite parts were the DITS machine, and all of the aliens, because I'm a sci-fi type of person. Not only this book, but the whole series is great for children to read. Each book makes you wonder what will happen in the next. I gave it a five-star-rating, because it was one of my favorite books ever, and because the author describes everything greatly in depth.
