Introducing a mesmerizing debut in the rich tradition of Marion Zimmer Bradley and the powerful narratives of Jacqueline Carey–a passionate tale of love and war in which the gods grant a common girl uncommon gifts… Before she was Firethorn, she was Luck, named for her red hair and favored by the goddess of Chance. A lowborn orphan, Luck is destined to a life of servitude. But when her mistress dies, Luck flees to the forest, where she discovers the sacred firethorn tree, whose berries bring her fevered dreams, a new name…and strange gifts. When she emerges from the woods, Firethorn is a new woman, with mysterious powers. And soon, in the chaos of the UpsideDown Days, when the highborn and the low trade places, Firethorn couples with the warrior Sire Galan, whom she follows to camp with the king’s army. There she learns that in her new role as a sheath, a warrior’s bedservant, she is but one step above a whore. By day she uses her gifts as a healer to earn a place among the camp’s women, and by night she shares Sire Galan’s bed, her desire equal to his. But the passion they feel for each other has no place in a world ruled by caste and violence. When her lover makes an ill-considered wager that chances her heart, the consequences are disastrous–and Firethorn will learn how hard it can be to tell honor from dishonor, justice from vengeance." "
