Before the massacre at Nariin, Enebish was one of the greatest warriors in the Sky King's Imperial Army: a rare and dangerous Night Spinner, blessed with the ability to control the threads of darkness. Now, she is known as Enebish the Destroyer - a monster and murderer, banished to a remote monastery for losing control of her power and annihilating a merchant caravan.

Guilt stricken and scarred, Enebish knows she should be grateful for this sanctuary. But when her adoptive sister, Imperial Army captain Ghoa, offers her a chance at reinstatement, she eagerly accepts. All she has to do is track down the notorious rebel leader, Temujin. But upon leaving the monastery, she discovers the tides of war have changed, and Temujin's rebels are the only ones standing between the people and death on the tundra.
