A Extroidinary Fantasy for All Ages Charlie Bone and the Invisible Boy is a excellent Non-Fiction book that is a great fantasy for all ages. When I first read this book I loved it. If you like Harry Potter you will love Charlie Bone the fantasy is very similar and I like this book just as much as the whole entire Harry Potter Series.As a serious series reader who has read every single fantasy series I think you should take my info very seriously. Jenny Nimmo is a great descriptive author that all children will love and be buying all of her entertaining books.
