Not his best "literary" work, but a great story and as always high concepts. Too bad they made a crappy movie out of it.
The Foundation Trilogy Boxed Set (Foundation, Second Foundation, Foundation and Empire)The Foundation Trilogy Boxed Set (Foundation, Second Foundation, Foundation and Empire) by Isaac Asimov
Buy used from: $19.99
I couldn't choose just one book from this set. This series makes up a not insignificant part the bedrock of modern science fiction. The Internet is nothing compared to the Encyclopedia Galactica.
Ender's GameEnder's Game by Orson Scott Card
Buy used from: $33.48
As with all good Science Fiction, this is more about characters and people than science. The story is nothing less than inspiring. The ending left me totally breathless. This is probably my favorite Sci-Fi book of all time.
Childhood's End (Del Rey Impact)Childhood's End (Del Rey Impact) by Arthur C. Clarke
Buy new: $10.20 / Used from: $2.09
Sad and Euphoric all at once. Big concept here. Clark is easily my favorite Author.
