The Commonwealth stands on the brink. As war engulfs the worlds of man, the Shapers are poised to strike at the very heart of human civilisation. The men and women of the Commonwealth Navy now find themselves at the forefront of a desperate battle for the very survival of the species against an enemy whose weapons and technology far exceed their own. Whilst the conflict rages, the Arkari plot their revenge. Stunned by the Shapers' savage assault on their worlds, they lick their wounds and shun the other races, instead focusing solely upon the task of striking back at the hated enemy. Meanwhile, thousands of light years away amidst the ruins of a dead planet, the relics of a long vanished race hold the clues to their own annihilation, and lead to the darkest secrets of both the Shapers and the Progenitors. The fate of the galaxy hangs in the balance.
