Darwinia
Robert Charles Wilson
 In March 1912, in the event some people called the "Miracle," Europe and parts of Asia and Africa, including its inhabitants, disappear suddenly overnight and are replaced with a slice of an alien Earth, a land mass of roughly equal outlines and terrain features, but with a strange new flora and fauna which seems to have followed a different path in evolution. Seen by some as an act of divine retribution, the "Miracle" affects the lives of people all around and transforms world history. The book describes the life and the adventures of Guilford Law, a young American photographer. As a 14-year-old boy, Guilford Law witnessed the "Miracle" as shimmering lights moving eerily across the ocean sky. As a grown man, he is determined to travel to the strange continent of Darwinia and explore its mysteries. To that end, he enlists as a photographer in the Finch expedition, which plans to travel up the river that used to be known as the Rhine and penetrate the bizarre new continent's hidden depths as far as possible. He lands in the middle of the jungle in the midst of nationalistic skirmishes, in which partisans attack and wipe out most of the party of the Finch expedition on the continent that they believe to belong to them. Law brought an unwanted companion with him, a mysterious twin who seems to have both lived and died on an alternate Earth unchanged by the Miracle. The twin first appears to Guilford in dreams, and he brings a message that Darwinia is not what it seems to be, and Guilford is not who he seems to be. A startling revelation soon arrives. By the end of the story, it is revealed to all the characters that it is really now the End of Time and that the Universe, the Earth, and all the consciousness that ever existed are really being preserved in a computer-like simulation known as the Archive. The Archive was built by a coalition of all the sentient beings in the Universe in an effort to save consciousness from death. However, "viruses" (parasitic artificial life-forms) known as Psions have invaded the system of the Archive. Guilford Law eventually learns that he and those like him serve as instruments in a cosmic struggle against the Psions for the survival of consciousness itself.
