When Avery Marsh’s lifelong secret is discovered, her parents send her away to Signet, a school for girls who are troubled with magic powers. She makes two fast friends in her new roommates, Peregrine “Pepper” Vanguard and Charlotte “Charlie” Evans. Together, the three girls navigate a school and a society determined to snuff out their magic for good.

Principles of Magic is a comic about friendship, burgeoning identities, and growing up in a world that isn’t quite ready for you yet. It’s about the powers inside all of us–the things that make us unique.
