About this ebook

The third and final book in The Nightfall Saga, the thrilling and action-packed epic fantasy series set in the world of The Demon Cycle, from New York Times bestselling author Peter V. Brett

“Heart-wrenching, smart, and modern . . . The Desert Prince has set a new standard for fantasy.”—Wesley Chu, author of The War Arts Saga

He is known as The Prince of Lies. The Father of Demons. He is Alagai Ka, the Demon King.

Though humanity won a hard-fought victory in its war against demonkind, the Demon King has escaped in search of a new queen to restart his dark hive, and has found signs of one on a distant shore.

But pursuing him are humanity's best hopes: Olive Paper and Darin Bales, whose legendary parents brought demonkind low once before. Olive and Darin will not rest until the demons are defeated, and so relentless is their hunt that they have followed Alagai Ka across the sea to a strange new land.

There they discover a culture unlike any they have never known, where demons live alongside humans as servants and companions. And there they meet the demon's masters--including a seductive prince who is drawn to Olive--who seem unable or unwilling to understand the danger they are in.

Because no human is safe from the Demon King's thirst for war--and every human must join the battle against his kingdom of death.
