A warrior and her dark sister join forces to dismantle and remake their embattled world in this epic fantasy saga from a Nebula Award–winning author. One of fantasy fiction’s preeminent practitioners, Jane Yolen creates a world and mythology that are richly enthralling and vibrantly alive in this acclaimed trilogy.   Sister Light, Sister Dark: Three-times orphaned and raised secretly by the acolytes of the goddess Alta, the child Jenna studies the ways of the warrior in preparation for the day that has been prophesied. For she may well be the goddess reborn who, with the aid of Skada—her mirror twin who can reveal herself only in darkness—is fated to bring devastation to the world.   White Jenna: Grown to young womanhood, the warrior Jenna offers her allegiance to the rightful king of the Dales—and her heart to his brother, Carum—joining the fight against the malevolent usurper Kalas. But the powerful despot appears unstoppable, dedicated to the destruction of the worshippers of Alta, the society of women in which the orphaned Jenna was lovingly raised.   The One-Armed Queen: Having fulfilled an ancient prophecy, the Queen of the Dales must now keep her faltering kingdom safe from a looming terror, and prepare her chosen successor—a one-armed orphan girl she discovered on the battlefield—for the grim responsibilities of rule.   A sweeping adventure of destiny, peril, magic, and romance, The Great Alta Saga is a magnificent feat of storytelling that ingeniously blends world-building, myth, poetry, and song.
