Poppy and Amelia didn't set out to be witches. That happened quite by accident, and it's a secret they must keep from their family and friends. Then there is Mia, the new girl in class. Pale, strange and deadly serious, she's in need of a couple of equally weird friends. Poppy and Amelia are happy to oblige.
Together, the three of them must thwart the plans of the sinister Miss Mortimer and her evil companions.
