Periodic transfusions of his blood can give other men a second, a third lifetime, perhaps more... Ben Richards will live longer than anyone has ever lived, but a transfusion to the wrong man could make him a prisoner for all time. And so he runs from the hunters, the human hounds who would cage him."
Ben Richards is a race driver with unique blood, which makes him immune to all known diseases, even old age. When a dying billionaire discovers Richard's secret, he is determined to get the blood, to keep himself alive.
