Hansa, Umber, and Cadmia have managed to fight their way out of the Abyss and return to Kavet, bringing with them the long-imprisoned Terre Verte.
Prince Verte is determined to return Kavet to its former magical strength and restore the royal reign of the Terre family. He has the ability; his stay in the Abyss has left him abundantly powerful. But it has also left him dangerously unstable.
But when Naples, once the strongest Abyssumancer in Kavet—and former ally of Verte—also returns from the Abyss, Hansa and the others realize it is not Verte they need to be concerned with. For the Abyssi and the Numini are engaged in their own grand war, one that is pouring across the veils of the realms. And if the magic-users cannot come together to stop them, the fabric of the mortal world will be destroyed, taking all of them with it.
Hansa Viridian, a captain in the elite guard unit tasked with protecting Kavet from sorcery, has always led a respectable life. But when he is implicated in a sorcerer’s crimes, the only way to avoid execution is to turn to the Abyss for help—specifically, to a half-Abyssi man he’s sworn he hates, but whose physical attraction he cannot deny.
Hansa is only the first victim in a plot that eventually drags him, a sorcerer named Xaz, and a Sister of the Napthol named Cadmia into the depths of the Abyss, where their only hope of escape is to complete an infernal task that might cost them their lives.
Henna is one of the most powerful sorcerers in the Order of Napthol, and her runes ’s runes tell her that the future of Kavet is balanced on the edge of the knife. The treaties between Kavet and the dragon-like race known as the Osei have become intolerable. The time has come for the royal house to magically challenge Osei dominion. Prince Verte, Henna' lover, is to serve as the nexus for the powerful but dangerous spell, with Naples--an untested young sorcerer from the Order of Napthol--a volatile but critical support to its creation.
Amid these plans, Dahlia Indathrone’s arrival in the city shouldn’t matter. She has no magic and no royal lineage, and yet, Henna immediately knows Dahlia is important. She just can’t see why.
As their lives intertwine, the four will learn that they are pawns in a larger game, one played by the forces of the Abyss and of the Numen—the infernal and the divine.
A game no mortal can ever hope to win.
