The HUGO and NEBULA AWARD-winning novel.

Isaac Asimov (1920-1992) was one of the most famous, honoured and widely read science fiction authors of all time. Born in Russia but raised in the USA, his career as an SF writer began in 1939 with 'Marooned Off Vesta', in AMAZING STORIES. His output was prolific by any standards - in a career spanning five decades, he wrote more than four hundred books, won six HUGOs, two NEBULAs and the SFWA GRAND MASTER AWARD, among many others, and provided pleasure and insight to millions of readers. He died in 1992 at the age of 72.
