When an ancient enchanter is released from the grounds of Bloor's Academy, threatening both of Charlie Bone's parents, the only way Charlie and his friends can defeat him is by finding the red king himself.

Charlie and his magically gifted friends and relatives work together to rescue Billy Raven, a young orphan, from a mysterious and dangerous couple who have adopted him.

Charlie and his friends unite to rescue Ollie, a boy who was turned invisible and made to live in the attics at Bloor's Academy more than a year ago, but they are hindered by a mysterious new student who lives with Charlie's aunts.

A new semester is beginning at Bloor's Academy, and danger is lurking around every corner.

Charlie hopes that the new term at Bloor's Academy will hold no nasty surprises. But then Henry Yewbeam appears, twisted through time from the icy winter of 1916.
