Query: WHAT A GREAT STORY!

I thought the book was exciting and interesting, because so much was happening! There are some sad bits in the story but don't let that put you off reading the book, because it is just great. The best bit is the happy ending - this is really, really, really GOOD! I think the age you shood start reading this book is at about seven and up.
