The capstone and crowning achievement of Heinlein's famous Future History, Time Enough for Love follows Lazarus Long through a vast and magnificent timescape of centuries and worlds. Heinlein's longest and most ambitious work, it is the story of a man so in love with Life that he refused to stop living it; and so in love with Time that he became his own ancestor.
People often call this novelist "the dean of science fiction writers", one of the most popular, influential, and controversial authors of "hard science fiction."
He set a high standard for science and engineering plausibility and helped to raise the standards of literary quality of the genre. He was the first science-fiction writer to break into mainstream, general magazines such as The Saturday Evening Post, in the late 1940s. He was also among the first authors of bestselling, novel-length science fiction in the modern, mass-market era.
