Two hundred thousand feet up, things go horribly wrong. An experimental low-orbit spaceplane breaks up on reentry, falling to Earth over a trail hundreds of miles long. And in its wake is the beginning of the most important mission in the history of space.

America needs energy, and Dan Randolph is determined to provide it. He dreams of an array of geosynchronous powersats, satellites that gather solar energy and beam it to generators on Earth, freeing America from its addiction to fossil fuels and breaking the power of the oil cartels forever. But the wreck of the spaceplane has left his company on the edge of bankruptcy.
Worse, Dan discovers that 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.

Now Dan has to thread a dangerous maze. The visible threats are bad enough: Rival firms want to buy him out and take control of his dreams. His former lover wants to co-opt his unlimited energy ideal as a campaign plank for the candidate she’s grooming for the presidency. NASA and the FAA want to shut down his maverick firm. And his creditors are breathing down his neck.

Making matters even more dangerous, an international organization of terrorists sees the powersat as a threat to their own oil-based power. And they’ve figured out how to use it as a weapon in their war against the West.
