'Sparky writing, clever plotting and biting wit [spin] an excellent tale' GUARDIAN, BOOKS OF THE YEARThe acceleration of Earth's spin begins gradually. At first, days are just a few seconds shorter than normal. Awareness of the mysterious phenomenon hasn't reached Tanner, a young man who flees his Alaskan hometown to work at CWC, a corporation which runs a network of massive aircraft that orbit the Earth, allowing people to visit Paris for an evening or order sushi from Japan. But a wave of social unrest presents challenges for CWC. That unrest sweeps up Winnie. A high school outcast, she falls in with a group of teen activists who blame the company for the planet's acceleration. As days on Earth quicken to twenty-three hours, then twenty, the sun rising and setting ever faster, causing violent storms and political meltdowns, Tanner and Winnie's stories spiral closer together.

Three-hour days. Two-hour days . . .

A propulsive exploration of capitalism, technology, and our place within a system that dwarfs us, Circular Motion is one of the most ingenious debut novels of our time.
