Which Witch?

Loved this book! I have read one other Eva Ibbotson, The Secrets of Platform 13, and thought it was just ok. This book was much better. I loved all the characters and her sense of humor. She made the witches and other characters seem just like everyday people in their problems, very funny. The plot is that a dark wizard, Arriman, is looking for a wife and will choose a bride by whoever performs the darkest piece of magic.
