The Door into Summer

A popular and enduring time travel tale by one of science fiction's all-time greats When Dan Davis is crossed in love and stabbed in the back by his business associates, the immediate future doesn't look too bright for him and Pete, his independent-minded tomcat. Suddenly, the lure of suspended animation, the Long Sleep, becomes irresistible and Dan wakes up 30 years later in the 21st century, a time very much to his liking. The discovery that the robot household appliances he invented have been mass produced is no surprise, but the realization that, far from having been stolen from him, they have, mysteriously, been patented in his name is. There's only one thing for it. Dan somehow has to travel back in time to investigate. He may even find Pete ... and the girl he really loves.

Robert A. Heinlein (1907 - 1988)
Robert Anson Heinlein was born in Missouri in 1907. He graduated from the US Naval Academy at Annapolis in 1929, serving as an officer until his discharge, for medical reasons, in 1934. In 1939 he turned to writing to supplement his Naval pension, selling his first story to John W. Campbell's Astounding magazine. He would go on to have a profound influence on Astounding, dominating the Golden Age of SF and shaping American science fiction for decades to come. He won multiple Hugos, an unprecedented six Prometheus Awards for libertarian SF and was the Science Fiction Writers of America's first Grand Master Award recipient. A deeply political writer, Heinlein is most closely associated with right-wing libertarianism, although Starship Troopers brought with it accusations of fascism and Stranger in a Strange Land is credited with being an influential text for the free love movement of the '60s. Acclaimed as one of the 'Big Three', alongside Arthur C. Clarke and Isaac Asimov, he was a giant of 20th century science fiction. Robert A. Heinlein died in 1988.
