Judas Unchained is the high-action concluding novel of the Commonwealth Saga from Peter F. Hamilton, one of the world's bestselling science fiction writers.

For hundreds of years the human race has been manipulated into starting a war that could destroy civilization. As Chief Investigator Paula Myo hunts down the terrifying creature behind the ploy, the invasion continues and dozens of worlds fall to the enemy.

Admiral Kime orders a defence with war-winning super-weapons, only to find that their adversaries have equally powerful armaments.

How they got them is the question. Has the Commonwealth's top-secret defence project been compromised, or is the truth even worse?

The Commonwealth Saga starts with Pandora's Star.
