This hefty novel returns to the universe of Vernor Vinge's 1993 Hugo winner A Fire Upon the Deep--but 30,000 years earlier. The story has the same sense of epic vastness despite happening mostly in one isolated solar system. Here there's a world of intelligent spider creatures who traditionally hibernate through the "Deepest Darkness" of their strange variable sun's long "off" periods, when even the atmosphere freezes. Now, science offers them an alternative... Meanwhile, attracted by spider radio transmissions, two human starfleets come exploring--merchants hoping for customers and tyrants who want slaves. Their inevitable clash leaves both fleets crippled, with the power in the wrong hands, which leads to a long wait in space until the spiders develop exploitable technology.
