Charlie Bone and the Invisible Boy by Jenny Nimmo

Charlie Bone and the Invisible Boy (The Children of the Red King, Book 3)

Rating:
This is the third book in the Charlie Bone series. Again, this book is just as good and appropriate as the others and I highly recommend it. In this book, Charlie discovers that a boy has been turned invisible and kept locked away in the Academies attic. Charlie and his friends must find a way to help this boy and prevent the Bloors from continuing their plans.
