The rise and fall of Khan Noonien Singh - Greg Cox

In 1974 an international consortium of scientists embarked on the Chrysalis Project, a top-secret experiment in human genetic engineering. Their goal is no less than the creation of a new, artifically improved breed of men and women: smarter, faster, stronger than ordinary human beings -- a super-race to take command of the entire planet.
Gary Seven, an undercover operative for an advanced alien species who knows all too well the apocalyptic consequences of genetic manipulation, is alarmed by the project's objectives. With his trusted agents Roberta Lincoln and the mysterious Isis, he will risk life and limb to expose Chrysalis and neutralise the awesome threat that the Project poses to Earth's future generations.
But he may already be too late. One generation of super-humans has already been conceived. As the years go by, Seven watches with growing concern as the children of Chrysalis -- in particular, one brilliant youth named Khan Noonien Singh -- grow to adulthood. Can Khan's dark destiny be averted? Or is Earth doomed to fight a global battle against his desire for conquest . . .
