Inherit the Earth — Brian Stableford

In the twenty-second century, biomedical nanotechnology has given everyone in the world long life and robust health. It is the New Utopia, and all live in the expectation that true immortality will soon be realized.

Damon Hart, son of the scientist responsible for much of the wonders of the new world, would rather forget his famous father and get on with his own life. But a shadowy terrorist group forces Damon to confront his heritage, launching a cat-and-mouse game that pits Damon against the terrorists, Interpol, and the powerful corporations that control the biotechnology of the future...a game Damon is ill-equipped to survive.
