In the heart of the vast Gouay Forest, Nina is raised in the ways of the witches. But she feels different, and she dreams of living fully as a boy--without having to give up magic, which only women are allowed to wield in this remote corner of the world. Finally, Nina decides to blaze a new trail--as Basil. Under this new identity, he leaves everything behind and sets out for Eclepsis, a prosperous city where a different caste of sorcerers--the Occultists--holds sway. As Basil strives to join their prestigious academy, he meets Alban and Madeleine, kindred spirits with whom he will share his dreams, his doubts... and his secrets.
