Anna’s science teacher really gets on her nerves – but is that a good enough reason to turn her into a giant rat?
With a big, angry rat on the loose, Anna soon realises she’s made a bad mistake. How will she turn it back into her teacher? And can she do it quickly, before anyone finds out that she’s an apprentice witch?
Anna can’t admit what she’s done, so no one can help her with her big, furry problem – or can they?
Sometimes even witches need a little help from their friends!
