Legendborn

Bree Matthews leaves home to attend her late mother's alma mater, where she uncovers a centuries-old supernatural war and the world of the Legendborn, a secret society made up of the magic-wielding, demon-fighting direct descendants of King Arthur and his knights. As she dives deeper, Bree becomes increasingly suspicious about what really happened the night her mother died, while discovering her own unique magical abilities, and having to answer to her fate in the impending war.
