Private William Mandella is a hero in spite of himself -- a reluctant conscript drafted into an elite military unit, and propelled through space and time to fight in a distant thousand-year conflict. He never wanted to go to war, but the leaders on Earth have drawn a line in the interstellar sand -- despite the fact that their fierce alien enemy is unknowable, unconquerable, and very far away. So Mandella will perform his duties without rancor and even rise up through the military's ranks... if he survives. But the true test of his mettle will come when he returns to Earth. Because of the time dilation caused by space travel the loyal soldier is aging months, while his home planet is aging centuries -- and the difference will prove the saying: you never can go home....

In the year 2043, the Ngumi War rages. Limited nuclear strikes have been used on Atlanta and two enemy cities, but the war goes on, fought by 'soldierboys' -- indestructible war machines operated by remote control by soldiers hundreds of miles away.

Julian Class is one of these soldiers, and for him war is truly hell. The psychological strain of being jacked-in to his soldierboy -- and the genocidal results -- are becoming too much to bear. Now he and his companion, Dr Amelia Harding, have made a terrifying scientific discovery, which could literally take the universe back to square one. Except that for Julian, the discovery isn't so much terrifying as tempting....

William Mandela is a genetic throwback, one of the small group of humans who fought and survived the Forever War. They returned to find humanity has evolved into a group mind called Man. Surrounded by a society that is too autocratic and intrusive, living a dull existence which cannot compare to the certainties of combat and feeling increasingly alienated, the veterans plan an escape to the future by means of space travel and relativity. But when their ship starts to fail, their journey becomes a search for the Unknown, the elusive entity responsible.
