Oil cartels and deadly terrorists threaten one man's work to generate clean energy in this science fiction thriller by the six-time Hugo Award–winning author. Two hundred thousand feet up, things go horribly wrong. The experimental low-orbit spaceplane Astro falls to earth over a trail hundreds of miles long. In the wake of this disaster is the beginning of the most important mission in the history of space. Entrepreneur Dan Randolph is determined to provide energy to a desperate world. He dreams of an array of geosynchronous powersats, satellites which gather solar energy and beam it to generators on Earth, breaking the power of the oil cartels forever. But the wreck of the experimental spaceplane has left his company on the edge of bankruptcy. Worse, Dan discovers the plane worked perfectly right up until the moment that saboteurs knocked it out of the sky. And whoever brought it down is willing and able to kill again to keep Astro grounded. . . .
