So what I need from you is a list of all science fiction and/or fantasy books you heartily recommend to anybody that were released AFTER 1989.
It doesn't have to have been popular on a bestseller list, you can second people's suggestions, or recommend things that were popular but you never personally understood. I'd also like it if you tell me why you liked them. I like books that make me think, and of course, a gripping novel is always good. No rules other than just sci-fi and fantasy released after 1989.
Oh, and I am addicted to Harry Potter, so that would be a redundant suggestion.
