Sirius is Thomas Trelone's great experiment - a huge, handsome dog with the brain and intelligence of a human being. Raised and educated in Trelone's own family alongside Plaxy, his youngest daughter, Sirius is a truly remarkable and gifted creature. His relationship with the Trelones, particularly with Plaxy, is deep and close, and his inquiring mind ranges across the spectrum of human knowledge and experience. But Sirius isn't human and the conflicts and inner turmoil that torture him cannot be resolved.
Olaf Stapledon, English novelist and philosopher whose "histories of the future" are a major influence on contemporary science fiction. He received a Ph.D. in philosophy and psychology from the University of Liverpool. In 1929 he published A Modern Theory of Ethics and seemed destined for an academic career, but after the success of his novel Last and First Men (1930), he turned to fiction. Stapledon also wrote for technical and scholarly reviews on ethics and philosophy. His other works include The Last Men in London (1932), Odd John (1935), Philosophy and Living (1938), Star Maker (1937), and Sirius (1944).
