The great blue berserker's destruction of the human colony Shubra was swift and merciless. And when it was over, Niles Domingo's daughter lay among the dead.

Now Niles Domingo is a man with a mission—vengeance at any cost.

With one small ship, Niles sets out against the great berserker called Leviathan, tracking it through the interstellar mists of the Milkpail Nebula. He is sure he is ready for anything, but nothing can prepare him for the astonishing discoveries that lie between him and his vengeance.

" In single-minded pursuit of their pre-programmed course of destruction, [the berserkers] attain a kind of perverse stature that makes them worthy stand-ins for the dark side of human nature ."—New York Times
