From the depths of space, a nightmare is coming.

The Alliance and its colonies have reached an uneasy peace, ending the destructive rebellion that had raged on a dozen worlds. No one expects the deal to last, and both sides are preparing for the next showdown.

But from the darkest depths, another challenge is coming, a horror almost unimaginable, one that will endanger the very survival of mankind and force not just the Alliance and its colonies, but all of the Superpowers, to join forces or face utter annihilation.

The Alliance Marines discovered dusty ruins on Epsilon Eridani IV, built by an ancient race, eons dead. But their mechanical guardians remain, and the disturbance of the long silent caves triggered an automated alert, one which has been heard. And answered.

Erik Cain and his Marines grimly take to the field once again, for what may be their final battle, against the robotic legions of the genocidal First Imperium. But facing a ruthless and technologically superior enemy may be easier than learning to fight alongside old enemies.

The First Imperium is book four of Jay Allan's bestselling Crimson Worlds series (over 1,000,000 sold).
