Ancestral Machines: A Humanity's Fire novel

It was named Bringer of Battles, three hundred worlds orbiting a single artificial star, three hundred battlefields where different species vie for mastery and triumph. It is a cage where war is a game -- brutal, savage and sudden. In this arena, all must bend the knee to the Lords of Permutation and the ancient sentient weapons with which they have merged. Or suffer indescribable agonies.

Trapped in this draconian crucible of death, Brannan Pyke, captain and smuggler, must fight his way to freedom.

Because in the Bringer of Battles, the game of war is played to the death and beyond.
