It's not easy being the only day girl at Turlingham Academy: Sophie misses out on all the midnight feasts and late night gossip. And when new girl Katy turns up it feels like she's bewitching all of Sophie's friends!

Katy's no witch, but there is a witch at Turlingham.

Katy comes from a long line of witch hunters whose job is to stop evil magic.

Sophie is going to help her - anything to get Katy out of her life and get things back to normal.

But what she discovers means nothing will ever be normal again!
