Adapt or Die

The old man looked at the large neon sign on the top of the roof entrance to the thirty-story building. INTERNATIONAL FREEZE, INC. He paused long enough to take one last look at the city of Los Angeles Major, a sprawling jungle of steel buildings clawing its way into the smog-filled sky like some perverse gray monster.
Through the thick, artificial eye lens, it was difficult to take in every detail, impress it on his mind. This image would have to last a long time -- if things worked out right.
Slowly he faced the entrance to International Freeze.
Hal Grant was about to enter a future world which could offer immortality . . A novel that reveals the price people pay when given the promise of prolonged life. Deep Freeze offered new worlds upon which to live ... and survive on. They would either adapt or die. But nobody told them the truth in the beginning. The promise of escape from dying of old age was all too tempting, and nobody could easily reject the idea of living forever...
And so it began for Hal Grant, aged hero of endless wars, who has come to that point in his life where he must decide to live a few months more or leap into the future ... and the unknown.... or death!
