Chronicles of Chrestomanci

After two centuries of feuding the powers of the two families of magicians in mythical Caprona are too weak to stop an incipient war, but the younger members of the families find a way. Gwendolyn Chant and her brother Cat find the Chrestomanci Castle family's magic powers difficult to counter with the inferior power of the Coven Street witches.

There are good witches and bad witches, but the law says that all witches must be burned at the stake. So when an anonymous note warns, "Someone in this class is a witch," the students in 6B are nervous—especially the boy who's just discovered that he can cast spells and the girl who was named after the most famous witch of all. Witch Week features the debonair enchanter Chrestomanci, who also appears in Charmed Life, The Magicians

...

Four separate incidents test the power of the Chrestomanci, a powerful enchanter with nine lives, to control misuses of magic on various worlds.

Two powerful young enchanters, Cat, the future Chrestomanci, and Marianne, who is being trained to be Gammer of the Pinhoes, work together as friends to try to end an illegal witches' war and, in the process, right some old wrongs.
