Charmed Life (The Chrestomanci Chronicles, Book 1)

Everybody says that Gwendolyn Chant is a gifted witch with astonishing powers, so it suits her enormously when she is taken to live in Chrestomanci Castle. Her brother Eric (better known as Cat) is not so keen, for he has no talent for magic at all.

However, life with the great enchanter is not what either of them expects and sparks begin to fly!
