Gordon R. Dickson (1923 - 2001)
Gordon Rupert Dickson was born in Alberta, Canada, in 1923 but resided in the United States from the age of thirteen. Along with Robert A. Heinlein, he is regarded as one of the fathers of military space opera, his Dorsai! sequence being an early exemplar of both military SF and Future History. Dickson was one of the rare breed of authors as well known for his fantasy as his SF - The Dragon and the George, the first novel in his Dragon Knight sequence, was shortlisted for the World Fantasy Award and won the British Fantasy Award. Dickson's work also won him three Hugos and Nebula. He died in 2001.
The black-clad mercenaries of the Friendly planets fought where their employer and their God dictated. On New Earth they pitted their fanaticism against the cold courage of the Dorsai.
And the implacable hatred of one man, Tam Olyn. Olyn saw his brother-in-law shot down before his eyes. His quest for vengeance took him across half the civilised worlds, to Cassida and Frieland, to St. Marie and back to New Earth. He met men of all the splinter groups into which mankind had evolved an he used them all to bring about his revenge - until Padma the Exotic taught him how to use his special powers, and the frightening knowledge of Final Encyclopaedia.
