2001: A Space Odyssey

A timeless masterpiece. What's not to love about classic science fiction like this? The beginning of the story is very strong and surprising. The buildup to the science fiction world is a masterclass. And the way the characterization is done, the reader can feel the broken, depressed psyche of each character, be it an AI. The ending is also very strong and surprising. I want to read the next books in the series, but it is not easy to pass such an epic saga.
