The Lesser Repository — Davaun Sanders

Mankind flourishes in a distant future ruled by densely populated Cities. After the biggest arrest of his life, Detective Ben Reiner plays a dangerous game with Maddix Wynn, psychopath cult member of the Cullers and suspected of killing thousands.

Eager to secure his own career in City Thirty-Eight, Reiner plays a dangerous bargaining game with the Culler. Maddix agrees to take Reiner to free an imprisoned child hostage on one condition: Reiner must show evidence of the Lesser Repository to his superiors.

The detective's gamble at being a hero fails when he discovers the hostage is no child at all. It's the prelude to the end of the human race. Now Reiner faces an unspeakable choice. Help the Culler complete his grisly work, or allow the world's last renewable resource to run out forever: the human soul.
