From the New York Times bestselling author of Avatar, the Last Airbender: The Rise of Kyoshi and Avatar, the Last Airbender: The Shadow of Kyoshi comes a thrilling new chapter in the Chronicles of the Avatar series and page-turning follow-up to Avatar, the Last Airbender: The Dawn of Yangchen

Common enemies make for strange friends . . .

Avatar Yangchen has succeeded in bringing a measure of stability to Bin-Er, but her successes have been limited to a single city, and rumors concerning Unanimity-a weapon capable of total obliteration-have led to increasing tensions among the Four Nations.

Desperate to restore diplomacy, Yangchen attempts to de-escalate hostilities between heads of state. But in the wake of a brutal assassination and the freeing of Unanimity, Yangchen is forced to bring Kavik-the trusted former companion whose betrayal crushed her-back into her fold.

As the Four Nations teeter on the brink of conflict and she begins to unravel the power-hungry Zongdu Chaisee's true agenda, Yangchen is forced to measure the worth of humanity, and how much can be sacrificed in the name of balance.
