Synopsis: From the back cover of the Tor paperback edition: "It happened one night, without warning: 90% of the human race disappeared without a trace, Vanished. There were no portents, no bodies, no clues as to where they went or whether they would ever return. Now, after years of violence spawned by fear and rage, an uneasy peace has been restored. Enclaves have formed and are defending each other against the fanatics still roving the land, renewing contact with the rest of the world, and trying to discover what caused the Vanishing."
