Diana Roark, CEO and adventuress, didn?t begin life as the richest person in human history. But she?s on a dangerous bio-prospecting mission in Earth?s deepest water when First Contact is made in the skies above the planet, and it changes her life forever. When she surfaces, after a near fatal accident, the aliens are gone. But they leave behind a system of Obelisks. Global financial failure follows First Contact. Diana risks her fortune to stabilize the planet, and in the process becomes immeasurably wealthy. But because of the Obelisks human beings stop aging?except for Diana, who mysteriously is the only person on the planet to continue growing older. And then after thirty years the aliens return. They've come to steal the planet, and only Diana, her life nearly over, stands in their way.
