David Brin and Gregory Benford come together again to issue a new edition of their bold collaboration about our near human future in space, planting our boots . . . and staking our destiny . . . on becoming the People of the Comet.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 and alter its orbit, to 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 possibly spark a new human destiny.Tremendously imaginative . . . a breathtaking effort from two of science fiction's brightest stars. — The San Diego Union
