Jeff Baker is a legend. He's an internationally-renowned inventor and philanthropist extraordinaire, and at seventy-eight he's given the world much of his genius. So in 2040, when Europe can finally rejuvenate a human being after decades of research, Baker becomes first choice for the gift of youth. And after eighteen months in a German medical facility, Jeff returns home looking no more than twenty. The successful rejuvenation feels like a miracle - until the glow starts to fade. Jeff's relationship with his ex-model wife changes drastically. He also sees his son Tim, and Tim's gorgeous girlfriend, in a whole new light. As his pensioner friends start to resent what Jeff has become, he becomes increasingly aware that the world is watching. For great gifts come at a price and he will be expected to contribute yet more brilliant research to justify his place in the history books. 'Peter F.
