Telemores, tiny proteins at the end of your DNA, define your life span. Telemores shorten as your cells divide, their length counts down your span on this earth. Sometime soon, someone will discover how to repair Telemores, how to turn the clock back on the human body. Yet what would be the purpose of living forever when such a medicine would fill the world with an infinity of clamouring humanity? Surrounded by 100 billion people fighting amongst the ruins of an ecologically exhausted planet, what would be the point of immortality? Jim Evans, retired super-rich trader, only wants to do good. He wants to fund research that will save lives. Professor Christopher Cardini has medical technology that will change the world. Through cell therapy he can even rejuvenate the dying. Yet there is something even Jim's money can't buy: protection from a brilliant but twisted mind.
