Non-fiction 'The Collapse of Chaos' - really changed the way I think about a lot of things in the world, although it is a bit of a brainbuster of a read. Ian Stewart and Jack Cohen wrote it along with a couple of other similar books.

Born on a Blue Day -. An autobiography of Daniel Tammet, an autistic savant polyglot with synesthesia. It sounds inaccessible, but it's a really cool insight into how his mind works, and the story is very readable and personal, getting into how he had to understand his sexuality as an autistic person who has difficulty expressing or understanding emotion as well as all the stuff about how he sees words and numbers as colours and the patterns they make.

Fiction would probably be Asimov's Foundation and Robot series. Not one book or even one series, but I loved all of them.
