Join the wonderfully weird Other hand family and their faithful guardian, Edgar the raven, and discover the dark secrets of Castle Other hand. Solstice and Cudweed are appalled to find their father has appointed a new school master. But things get even worse when the grumpy, viciously mean teacher actually arrives. The Other hand children are sure there's something more to him than meets the eye - the trouble is, who will believe them? No one it seems. Except, perhaps, Edgar.
