"Keegan and Tristen Kozinski have created, in The City of Locked Doors, a truly unique work that is quite different from anything else I have read." Steven Robinson, Reader's Favorite.

Born hundreds of years ago, before the world fell into madness, Noir and Alighieri were hated and feared for their power. But even in this devastated world, there are always those who covet power.

Thus, the brothers were hunted, betrayed, and killed for their power.

But death's grasp on this world is tenuous and Noir endured. Alighieri did not; him, they plundered and butchered, carving talismans of power from his blood and bone before burning the rest into true death.

Now, Noir is alone and going mad in a world where the night turns every human into monsters, and the dregs of civilization live in the thrall of deific Tyrants. He persists, however, and he knows who killed his brother. They will remember why they feared him.

Noir begins his hunt in the steam-choked edifices of the prison city Umbras, domain of the Tyrant Lock-And-Key. Only, the Tyrant has disappeared, leaving the city teetering on the edge of a power vacuum that will destroy it.
