The Pinhoe Egg

The Pinhoe Egg is a children's fantasy novel by British author Diana Wynne Jones published by HarperCollins Children's Books in 2006. It was the last published of the seven Chrestomanci books (1977 to 2006).

It revisits Chrestomanci Castle and the character of Cat Chant from her first Chrestomanci book, but also introduces the character of Marianne Pinhoe, who lives in the village near the castle and whose family practices a rather different sort of magic from any that Chrestomanci or his charges have encountered.

The Chrestomanci books are set in a parallel world and are collectively named after a powerful enchanter and British government office named Chrestomanci, who supervises the use of magic. The Pinhoe Egg is set during the tenure of Christopher Chant, who is Chrestomanci in five of the seven books and is often called Chrestomanci as a personal name.
