Dark as Day is set in the universe Sheffield created for his brilliant novel Cold as Ice. It is a universe where humanity is still limited to our solar system, and was nearly wiped out entirely in an interplanetary war that ended some thirty years before Dark as Day begins. But not quite destroyed. In this sequel, Charles Sheffield returns to the human-settled solar system in the years after the Great War. That interplanetary war is over now, but there are still horrifyingly dangerous weapons caches to threaten human survival. The solar system is finally recovering, though. The Earth is returning to habitability, at least in the Southern Hemisphere. The Northern Hemisphere, target of dreadful biological weapons, remains uninhabitable. Mars has a small population, and the asteroids and the moons of Jupiter and Saturn are thriving centers of trade and research. On one of those moons, Alex Ligon, scion of a great interstellar trading family, has turned his back on his family business in favor of the mathematics of statistical modeling. He has developed a wonderfully accurate new population model and cannot wait until the newly reconstituted "Seine," the interlinked network of computers that spans the planets and moons and asteroids, comes back on-line. But when it does, and he extends his perfect model a century into the future, it predicts the complete destruction of the human race. On another moon, the search for extraterrestrial intelligence goes on, undaunted by generations of failure. And to her amazement, Millie Wu, a young genius newly recruited to the project, has found a signal.. a signal that is coming from outside the solar system. Deciphering this transmission will be the greatest challenge ever presented to the Puzzle Network.
