Judas Unchained is the concluding portion of Peter F. Hamilton’s blockbuster space opera, The Commonwealth Saga.

After hundreds of years secretly manipulating the people, the Starflyer alien has succeeded in engineering a war which should result in the destruction of the Intersolar Commonwealth. Now, thanks to Key Investigator Paula Myo, the Commonwealth’s political top notch finally acknowledges the Starflyer’s life, and puts jointly an unlikely collaboration to locate this enigmatic and terrifying alien.

The invasion from Dyson Alpha continues with dozens of Commonwealth worlds falling to the enemy. The navy battles back with what it is convinced to become war-winning superweapons, only to find the alien fleet offers equally powerful weaponry. The way the aliens got them may be the query which haunts Admiral Kime. Can it be that this Commonwealth’s top-secret defence project has been jeopardized from the Starflyer’s agencies, or may be the truth a whole lot worse?
