John Varley’s first novel, and also the first one in the Eight Worlds Universe, has an interesting and intricate, premise. Four hundred years previously, enigmatic aliens invaded the Earth, and most of humanity died off. Humans now live scattered around the solar system, dependent at least in part on technological know-how beamed from faraway Ophiuchi. No one knows who or what is beaming the data, except that it is finely attuned to the needs of humans. Lilo, a genetic engineer condemned to death for taking her reasearch into unethical directions, is embroiled in a plot to retake the Earth for humanity. Her multiple journeys throughout the Solar System are mirrored by journeys of discovery into her own humanity. As multiple clones are branched off, Varley explores how Lilo’s personality differs given her environment, and yet retains its basic values.
This one is clearly written during the seventies, as there is a lot of nudism and casual sex.
The book seems to beg the question: “What’s the point of retaking the Earth when life is an eden out here?” The ending does take the clear stance that we have to proactively defend our existence, and not take our survival as a spieces for granted. I very much enjoyed this book, which packs a lot of story into a mere 170 pages.
