Underworld

by Apollos Thorne

Summoned into the lightless tunnels of the Underworld along with hundreds of other teenagers — as prey — Elorion has one absurd advantage: a System interface and the stubbornness to grind it. Staying alive means leveling faster than the things hunting him, and forging his fellow captives into something like an army. Apollos Thorne's claustrophobic descent-and-ascent power fantasy.
