Earth is the latest science fiction novel from multiple Hugo Award winner Ben Bova, author of Apes and Angels and SurvivalA wave of lethal gamma radiation is expanding from the core of the Milky Way galaxy at the speed of light, killing everything in its path. The countdown to when the death wave will reach Earth and the rest of the solar system is at two thousand years.Humans were helped by the Predecessors, who provided shielding generators that can protect the solar system. In return, the Predecessors asked humankind's help to save other intelligent species that are in danger of being annihilated. But what of Earth? With the Death Wave no longer a threat to humanity, humans have spread out and colonized all the worlds of the solar system. The technology of the Predecessors has made Earth a paradise, at least on the surface. But a policy of exiling discontented young people to the outer planets and asteroid mines has led to a deep divide between the new worlds and the homeworld, and those tensions are about to explode into open war.

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 it its wake is the beginning of the most important mission in the history of space.America needs energy, and Dan Randolph is determined to give it to them. He dreams of an array of geosynchronous powersats, satellites which 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, Astro Manufacturing, 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.A sweeping mix of space, murder, romance, politics, secrets, and betrayal, Powersat will take you to the edge of space and the dawning of a new world.
