The Mongol Empire is fractured but the unstoppable warlord, Timur, has the potential to repair the damage and conquer everything in his path.

After being manipulated, Temujin has severed all ties with the Kozan and embraced his heritage. As the new ruler of the Ilkhanate he is determined not to repeat mistakes made his father. But few believe Temujin is up to the task, least of all his father, as a Khan must be utterly ruthless.

The new Persian army needs time before it's ready, forcing Kaivon and Esme to support Temujin and the Ilkhanate. Conducting dangerous missions across enemy lines they hope to slow Timur's conquest.

Kokochin seeks to make amends by helping others fight back against the Mongols. After attracting the attention of a killer, she struggles with her darker instincts to protect herself and those around her.

The world is on the verge of a war, unlike any that have come before, but who will emerge triumphant in a world of magi, spies and conquerors?

The final instalment from bestselling author Stephen Aryan's sees an epic conclusion to The Nightingale and the Falcon trilogy.
