James McLanahan Bradley is leading a team of engineers designing Starfire, the world's first orbiting solar power plant. It will deliver unlimited and inexpensive electricity to Earth, and can also power the Moon, spacecraft and asteroids. But the U.S. President's plans to militarize and industrialize Earth's orbit sparks an arms race in space that rivals the Cold War. Bradley and his team are caught at the center of a battle that threatens to become all-out global war for control of space.
