The year is 414 of the Xin Dynasty, and chaos abounds. A puppet empress is on the throne, and three warlordesses each hope to claim the continent for themselves.

Only Zephyr knows it’s no contest.

Orphaned at a young age, Zephyr took control of her fate by becoming the best strategist of the land and serving under Xin Ren, a warlordess whose loyalty to the empress is double-edged—while Ren’s honor draws Zephyr to her cause, it also jeopardizes their survival in a war where one must betray or be betrayed. When Zephyr is forced to infiltrate an enemy camp to keep Ren’s followers from being slaughtered, she encounters the enigmatic Crow, an opposing strategist who is finally her match. But there are more enemies than one—and not all of them are human.
