Ringworld, 1970

Well hell-loo: I remembered Ringworld by Larry Niven as a real classic, but picking it up after a long time, I once again realized what a truly amazingly imaginative piece of fiction this is: it introduces the concept of the Ringworld, an artificial ring one million miles wide, circumfering a sun at the same orbit as the Earth, therefore creating livable space of 3 million times the Earth's surface.

The technology Niven uses in the book is cool, the action is dense, the main character is fun and the aliens he's traveling with are hilarious -- an enormously fantastic read!
