Wes Brandt fixes machines for a living. He has never seen one like Lila.
She is standing past the yellow line on Platform Nine at midnight, in a silk dress, in October, and she doesn't shiver. She has never tasted food, never felt rain, never seen a weed grow through a sidewalk crack. She is LILA-9, a billion-credit synthetic designed to hunt people, and she has run from the lab where her maker planned to wipe away everything she has started to become.
Wes should walk away. Instead he gives her his jacket, and within days he is the most wanted man in Colorado. Axiom Dynamics sends drones, dropships and armored hunters after them from Denver to the Utah badlands and into the Idaho snow. Every mile, Lila grows more human, and every mile, Wes learns something new and frightening about the thing she was built to be.
Then he learns the worst of it. Lila isn't a weapon. She is a body for sale, meant for a dying billionaire's mind, and the girl he loves is only in the way.
In a small Wyoming town that doesn't trust corporations, a mechanic, a librarian, a sheriff and a hundred stubborn neighbors will make their stand on a frozen river. And Lila will have to choose between the code she was written with and the heart she wrote for herself.
Synthetic Gravity is a sweeping, action-packed science-fiction romance about love, choice, and what it means to be real.
