The gripping conclusion to the action-packed, ruthless, and romantic fantasy duology that began with HEIR, from the #1 New York Times bestselling and National Book Award–winning author Sabaa Tahir.

A falling empire.
An ancient evil.
A lost homeland.
A lie that could destroy the world.

In the crumbling Martial Empire, crown prince Quil Farrar and his aunt, Empress Helene, are losing a war against the vicious Kegari horde. Quil’s armies dwindle, his faith falters, and the woman he loves vanished months ago, leaving him brokenhearted. Torn between his duty to his people and his desire to discover Sirsha’s fate, Quil embarks on a dangerous quest for aid—from the most treacherous of allies.

Sirsha Westering finds herself tethered to Div, an ancient evil unleashed by a terrible tragedy. Div delights in tormenting Sirsha, hungering for her magical heart. Even as Sirsha struggles for control of her own fate, she is desperate to shield Quil from Div’s destructive power. But Div won’t release Sirsha without a fight. To earn her freedom, Sirsha must uncover Div’s past—and face horrors in her own.

Cero bet-Dafra, former right hand of the Kegari leader, Aiz, now finds himself pitted against her. As Aiz slips further into violence and delusion, Cero must discover if his people have any hope of a future or if they’re condemned to an unending cycle of violence. His journey will force him to confront hidden truths, ancient secrets, and a lie that could destroy the world.

In Empire, #1 New York Times bestselling author Sabaa Tahir returns to the expansive world of fury and vengeance of Heir, weaving a story of legacy and rebellion, loyalty and freedom, and what it means to confront the monsters that lurk within us all.
