Charlie Bone and the Castle of Mirrors is the fourth book in the Children of the Red King series by Jenny Nimmo. I enjoyed this book, even though it is not my favorite in the series. Charlie Bone is back for a new semester at Bloor’s Academy. This is a school for students with magical powers. Charlie Bone knows that he possesses magical ability, but he still has not fully learned the extent of his endowment.
In this book, Charlie meets some new characters. Billy Raven is an orphaned boy who has been adopted by a couple named Mr. and Mrs. de Grey. The de Greys have magical powers, but it turns out that they are evil. They force Billy to sign papers that contain oaths, which would compel him to do things against his will. Billy becomes imprisoned in a mysterious place called The Passing House. Mr. de Grey uses his magic to create a force field that prevents Billy from escaping.
My favorite part of the story is when Charlie Bone and his friends help Billy to escape from The Passing House. They take Billy to the house of one of Charlie’s friends, named Gabriel Silk. At Gabriel’s house, the papers with the oaths suddenly come to life, and attack Billy and his friends. The friends need to join forces with their magical powers to rescue Billy from the evil magic of the de Greys.
One of my favorite things about this book is the development of the characters. I especially liked to read about Charlie’s friends, Lysander Sage and Tancred Torsson. They have special powers that prove to be very useful in this story. This particular book may not be quite as exciting as some of the others in the series, but I definitely still enjoyed it. I am not really sure why it is called The Castle of Mirrors, because that did not seem to be the most important part of the story. Still, I am glad to have read this book, and I would recommend it to anyone who enjoys the Charlie Bone series.
