I was disappointed in this book. When I saw it in the listings - marked as a "mass market paperback - I thought it was one of the usual 200-300 page 4" X 7" paperbacks like you see in the supermarkets. Therefore, I was highly disappointed when I received something that looked like it had been written to encourage an early teenager or preteen to read by presenting a subject that would interest them. The story followed its general story line well and was still fairly interesting. Had the book been what I thought I was ordering, I would have considered it very good. I would have given it 4 or 5 stars.
