The demon king Asroth has been freed from his iron prison. Now, alongside his dark bride, Fritha, he plans to conquer the whole of the Banished Lands. In the shadows of Forn Forest, Riv and the surviving Ben-Elim desperately search for a way to unite those who remain against Asroth's vast army. Far in the west, Drem is with the Order of the Bright Star, besieged by a demon horde. Their fragile defenses are on the brink of shattering, but they know that it is better to fight and die than to live without hope.

The Ben-Elim, a race of warrior angels, once vanquished a mighty demon horde. Now they rule the Banished lands. But their dominion is brutally enforced and their ancient enemy may not be as crushed as they thought. In the snowbound north, Drem, a trapper, finds mutilated corpses in the forests—a sign of demonic black magic. In the south, Riv, a young, tempestuous soldier, discovers a deadly rift within the Ben-Elim themselves. Two individuals with two world-changing secrets. But where will they lead?

The emperor's reign has lasted for decades, his mastery of bone shard magic powering the animal-like constructs that maintain law and order. But now his rule is failing, and revolution is sweeping across the Empire's many islands. Lin is the emperor's daughter and spends her days trapped in a palace of locked doors and dark secrets. When her father refuses to recognise her as heir to the throne, she vows to prove her worth by mastering the forbidden art of bone shard magic.

In Daretana’s greatest mansion, a high imperial officer lies dead—killed, to all appearances, when a tree erupted from his body. Even here at the Empire’s borders, where contagions abound and the blood of the leviathans works strange magical changes, it’s a death both terrifying and impossible. Assigned to investigate is Ana Dolabra, a detective whose reputation for brilliance is matched only by her eccentricities. Rumor has it that she wears a blindfold at all times, and that she can solve impossible cases without even stepping outside the walls of her home.

Sancia Grado is a thief, and a damn good one. And her latest target, a heavily guarded warehouse on Tevanne’s docks, is nothing her unique abilities can’t handle. But unbeknownst to her, Sancia’s been sent to steal an artifact of unimaginable power, an object that could revolutionize the magical technology known as scriving. The Merchant Houses who control this magic - the art of using coded commands to imbue everyday objects with sentience - have already used it to transform Tevanne into a vast, remorseless capitalist machine.
