Diana Roark didn’t begin life as the richest person in human history. All she ever wanted to do was solve impossible problems—like her father had. She's on a dangerous bio-prospecting mission in Earth’s deepest ocean when aliens orbit to make First Contact, and she surfaces after a near fatal accident to find the aliens gone, and every human alive Augmented—except for her. After Augmentation humanity no longer ages, and all basic needs are dispensed free from alien Obelisks, creating a cascade of economic failure around the globe. When Diana invests everything to stabilize Earth's finances, she ends up the richest person in human history, though she is still the only human alive who ages. And then, after thirty years, the aliens return. Only this time they’re not feeling generous. They’ve come to take the planet, and the only person standing in their way is Diana.
