When 17-year old Kai is exposed as a female sorceress–a moonburner, she knows the punishment is death. Despite the odds against her, Kai escapes her fate and undertakes a harrowing journey to a land where moonburners are revered and trained as warriors.

But the moonburner citadel is not the place of refuge and learning that Kai imagined. The ongoing war against the male sorcerers, or sunburners, has led the citadel leadership down a dark path that could spell the end of all magic. Armed with a secret from her past and a handsome but dangerous ally in the sunburner prince, Kai may be the only one able to prevent the destruction of her people.
