They are the light against the darkness.
The steel against the necromancy of the Druj.
And they use demons to hunt demons….
Nazafareen lives for revenge. A girl of the isolated Four-Legs Clan, all she knows about the King's elite Water Dogs is that they bind wicked creatures called daevas to protect the empire from the Undead. But when scouts arrive to recruit young people with the gift, she leaps at the chance to join their ranks. To hunt the monsters that killed her sister.
Scarred by grief, she's willing to pay any price, even if it requires linking with a daeva named Darius. Human in body, he's possessed of a terrifying power, one that Nazafareen controls. But the golden cuffs that join them have an unwanted side effect. Each experiences the other's emotions, and human and daeva start to grow dangerously close.
As they pursue a deadly foe across the arid waste of the Great Salt Plain to the glittering capital of Persepolae, unearthing the secrets of Darius's past along the way, Nazafareen is forced to question his slavery—and her own loyalty to the empire. But with an ancient evil stirring in the north, and a young conqueror sweeping in from the west, the fate of an entire civilization may be at stake…
Visionary. Alchemist. Savior. Saint.
The Prophet Zarathustra has been called many things. Now he spends his time drawing pictures of weird-looking goats. That's what happens when you've been stuck in a prison cell for two hundred years. But the man who might be mad, and is definitely supposed to be dead, has suddenly become very valuable again.
It's only been a few weeks since Nazafareen escaped the King's dungeons with her daēva, Darius. She hoped never to set foot in the empire again, but the search for the Prophet has led them to the ancient city of Karnopolis. They have to find him before Alexander of Macydon burns Persepolae, and Darius's mother with it. But they're not the only ones looking.
The necromancer Balthazar has his own plans for the Prophet, and so does the sinister spymaster of the Numerators. As Nazafareen is drawn in to a dangerous game of cat and mouse, her newfound powers take a decidedly dark turn. Only the Prophet understands the secret of her gift, but the price of that knowledge may turn out to be more than Nazafareen is willing to pay…
Persepolae has fallen.
Karnopolis has burned.
As the dark forces of the Undead sweep across what remains of the empire, Nazafareen must obey the summons of a demon queen to save Darius's father, Victor. Burdened with a power she doesn't understand and can barely control, Nazafareen embarks on a perilous journey through the shadowlands to the House-Behind-the-Veil. But what awaits her there is worse than she ever imagined…
A thousand leagues away, Tijah leads a group of children on a desperate mission to rescue the prisoners at Gorgon-e Gaz, the stronghold where the oldest daevas are kept. To get there, they must cross the Great Salt Plain, a parched ruin occupied by the armies of the night. A chance encounter adds a ghost from the past to their number. But will they arrive in time to avert a massacre?
And in the House-Behind-the-Veil, Balthazar and the Prophet Zarathustra discover that they have more in common than meets the eye. But is it enough to salvage the necromancer's bloodstained soul and thwart his mistress's plans?
As a final showdown looms between Alexander the Great and Queen Neblis, the truth of the daevas' origins is revealed and three worlds collide in this thrilling conclusion to the Fourth Element series.
