Superstorms flatten cities. Coastlines collapse. Climate change is no longer theoretical—it is lethal. When a near-apocalyptic storm nearly kills their family, teenage siblings Jimmy and Lizzie Marshall urge their brilliant but reluctant father, nanoscientist Greg Marshall, to deploy a technology before he’s brave enough to release it.
WhiteGrass—a self-replicating nanotechnology capable of removing carbon from the atmosphere is the parent technology. It saves golf courses and ski resorts and the towns they serve. Icarus could reverse climate change on a global scale. It could also reshape global power forever.
To protect the technology, Greg and his wife Ginny, an elite AI expert, reprogram the world’s most advanced humanoid android, Valada. Designed as property—an object without rights—Valada begins to evolve, developing emotional awareness, moral judgment, and something disturbingly close to humanity.
As governments unravel and climate disasters accelerate, a covert alliance of oligarchs, corporations, and political power brokers moves to seize WhiteGrass/Icarus for themselves. Led by the President of the United States, the syndicate will stop at nothing—surveillance, blackmail, assassination—to control the technology that could save the world or enslave it.
They deploy their own deadly android.
Now the Marshalls are trapped in a global sci-fi political conspiracy, hunted by forces with unlimited resources, as skyscrapers fall, cities burn, and artificial intelligence begins to ask questions no human is prepared to answer.
At its core, WhiteGrass is a gripping near-future climate change thriller about family survival, technological power, and the terrifying moment when artificial intelligence stops serving humanity—and starts judging it.
Blending nanotechnology science fiction, AI humanoid emotional evolution, and hard-science realism, WhiteGrass delivers relentless pacing, cinematic stakes, and deeply human emotion. It is a story about parents willing to risk everything to protect their children—and a world forced to confront whether it deserves saving at all.
Perfect for fans of near-future disaster thrillers, technothrillers with political intrigue, and science fiction where artificial intelligence becomes human, WhiteGrass is a powerful warning—and an unforgettable ride.
