The Worst Witch
Mildred Hubble returns to Miss Cackle's Academy for Witches for the Summer Term of her second year. Instead of the usual black-and-grey-checked dresses, Miss Hardbroom persuaded Miss Cackle to change them to plain black. After crash-landing in a pile of snow and meeting up with her best friends, Maud Spellbody and Enid Nightshade, Ethel Hallow appears and tells Mildred that Miss Cackle wants to see her.
