Gregory Benford and David Brin come together in this bold collaboration about our near human future in space

Prescient and scientifically accurate, Heart of the Comet is known as one of the great hard SF novels of the 1980s. First published in 1986, it tells the story of an ambitious manned mission to visit Halley's Comet, alter its orbit, and mine it for resources. But all too soon, native cells—that might once have brought life to Earth—begin colonizing the colonists. As factions battle over the comet's future—and that of Earth—only love, courage, and ingenuity can avert disaster and spark a new human destiny.
