Blurb

The Sirian Experiments is a 1980 science fiction novel by Nobel Prize in Literature-winner Doris Lessing. It is the third book in her five-book Canopus in Argos series and continues the story of Earth's evolution, which has been manipulated from the beginning by advanced extraterrestrial civilisations. It was first published in the United States in December 1980 by Alfred A. Knopf, and in the United Kingdom in March 1981 by Jonathan Cape. The book was shortlisted for the Booker Prize in 1981.
The Sirian Experiments relates directly to the first book in this series, Shikasta, which is the history of the planet Shikasta under the influence of three galactic empires, Canopus, Sirius and their mutual enemy, Puttiora. Shikasta is told from the Canopean viewpoint. The Sirian Experiments tells the story of Shikasta from the Sirian point of view and describes the activities of Sirians on the planet and the strained relations of Sirius with Canopus.
