The Worlds of Chrestomanci
The Worlds of Chrestomanci by Diana Wynne Jones wasn't that good a book .It is about a boy called Cat who is learning how to be a wizard and another boy comes from Italy but Cat doesnt like the boy .They go away and meet an evil spell caster and get into lots of trouble.
My favourite bit is when Cat and Tonino are in the hospital with spider man and spider man gets slapped.It is funny.
