Shout-Out: A Perfect Machine by Brett Savory

Henry Kyllo is a Runner, a member of a secret society called the Inferne Cutis. Every day he is chased through the city by Hunters whose goal is to fill him with bullets. It is a secret war steeped in history, tradition, and mutual fear.

Rumours abound about what happens when a Runner achieves ascension, but it has supposedly never happened before, so no one knows for sure. Except that it has happened before. And it is happening again.

This time, to Henry Kyllo.
