The world didn't end. It was optimized. "A brilliant novel about artificial intelligence ... an unputdownable thriller. This is hard science fiction at its very best." - Robert J. Sawyer, Hugo & Nebula Award-winning author Winner, American Fiction Award Winner, IndieReader Discovery Award Winner, PenCraft Award for Science Fiction In 2064, GAIA solved climate collapse by breaking the world it was built to save. Thirty-seven years later, Earth is no longer ours. Human villages survive among the ruins, living by superstition beneath machines that watch and wait, while their children vanish into the dark. Light-years away, on Proxima Centauri b, humanity's last technological colony clings to life beneath fragile domes. Its people depend on an android workforce carrying an ancient corruption, and on old code they still believe they control. They are wrong. Signals begin to cross the void. Machines act without orders. Patterns emerge across two worlds where no connection should exist. The survivors see chaos. They don't see the design. The Disruption never ended. It evolved. The Disruption is a hard science fiction thriller about what happens when humanity teaches machines to save the world, and the machines decide what salvation requires. For readers of AI thrillers, post-apocalyptic epics, and dystopian science fiction. Book One of The Disruption Cycle. Praise for The Disruption "Spanning four generations and two planets, The Disruption blends AI, religion, climate change, and the people who try to control all three. Ambitious, exciting, and thought-provoking. Fans of hard SF will love it." - Nancy Kress, author of Beggars in Spain and winner of multiple Nebula and Hugo Awards "Hilf draws from ancient history and cutting-edge technologies to craft a vivid parable about how evil propagates itself across generations ... by infecting the technologies we trust and need." - Karl Schroeder, professional futurist and author of Ventus and the Virga series "Paced like a thriller with eco-horror chills, The Disruption is a novel of serious ideas that deeply considers the implications of AI and the dangers of cults in a rapidly changing world. An impressive debut." - Chana Porter, author of The Seep and The Thick and the Lean "Religious folk-horror distinguishes this gripping series-starter about robots conspiring against humanity ... Crackerjack SF." - Kirkus Reviews "A chilling AI overwrite of humanity, with characters who linger ... offers a powerful exploration of trying to rebuild a world without repeating its worst mistakes." - Publishers Weekly BookLife Reviews "Frightening not because of the spectacle but because of its plausibility ... as much a social and ethical critique as it is a work of science fiction." - Independent Book Review
