Earth has been destroyed, the entire solar system turned to dust by a cataclysmic event known as the Fracture. Now, the last survivors of humanity live on vast arkships drifting through the Cluster, fighting for survival in this hostile, ever-changing environment.

When the arkship Obsidian is attacked, Wynn awakes in an escape pod fleeing from a huge space battle, unable to remember who he is. Aided by Bara, an engineer who survived the attack, Wynn finds himself hunted by a killer robot, the forces of a rival arkship, and the mysterious Church of the Infinite. Can Wynn survive long enough to unlock his lost memories, discover his true identity and take his revenge?

Having spent two years in hiding, Wynn is desperate to test out his newly constructed arkship, the Vengeance, and put a stop to the expansionist ambitions of the House of Draig. But Wynn's first skirmish exposes his lack of experience, and his plans for revenge soon lie in ruins. Hunted, outnumbered, and on the brink of extinction, Wynn must find a way to save his family and friends before the House of Kenric is lost forever. 

Recovering from the war with the House of Draig, Wynn must forge new alliances with other families and their arkships, if they are to survive. But the threat from the Draig fleet has not gone away, and Wynn finds himself thrust into the heart of new, more dangerous dilemma.

As the balance of power shifts across the Cluster, Wynn must choose between a life of peace on the fringes, or all-out war with the House of Draig and its growing alliance.

The Draig civil war rages on, threatening the stability of the entire Cluster,but when a face from the past returns to unify the disparate factions, Valine must form an alliance with her old enemy, Prince Halstead, to counter the growing menace.
 
Meanwhile, as the Church of the Infinite prepares to anoint its new leader, the arkships of the Cluster converge on the Firmament, the mysterious station orbiting in the ruins of Earth. When the rival families and clans come together, the danger of all-out war becomes unavoidable, and Halstead is forced to sacrifice everything he holds dear and stand alone against the rising forces of evil.
