When Clary Fray's mother has disappeared, Clary joins a band of Shadowhunters; demon killing hunters, and gets caught up in a plan to save the world.

On Willa Ward’s twelfth birthday, she inherits a beautiful charm necklace that belonged to her mother, who was a witch. She soon learns 2 bad witches, Wilma and Wanda are after her locket so they can have ultimate power, and she alongside her best friends Scout and Lily turn into cats to escape.

As a follow-up to The Worst Witch serial, we follow Mildred Hubble in her first year at Weirdsister College, a university for students of magic. Similar to her adventures at Cackle's, Mildred usually messes up, but saves the day in the end. The series has a darker side than The Worst Witch, with evil creatures and a possible doomsday.
