The Saint of Bright Doors

Fetter was raised to kill, honed as a knife to cut down his sainted father. This gave him plenty to talk about in therapy.

He walked among invisible powers: devils and anti-gods that mock the mortal form. He learned a lethal catechism, lost his shadow, and gained a habit for secrecy. After a blood-soaked childhood, Fetter escaped his rural hometown for the big city, and fell into a broader world where divine destinies are a dime a dozen.

Everything in Luriat is more than it seems. Group therapy is recruitment for a revolutionary cadre. Junk email hints at the arrival of a god. Every door is laden with potential, and once closed may never open again. The city is scattered with Bright Doors, looming portals through which a cold wind blows. In this unknowable metropolis, Fetter will discover what kind of man he is, and his discovery will rewrite the world.
