I made this topic on another forum and got quite a few good suggestions, so I figured I would make it here too. A few more good books to add to the list couldn't hurt.
I'm really interested in reading some good sci-fi books, but whenever I look online all I see are recommendations for Asimov, Clarke, Heinlein, etc. That's great and all, but I have absolutely no interest in the science behind the technobabble. Any scientific explanation beyond "it goes ding when there's stuff" tends to bore me at record speed.
Basically I'm looking for some good, intelligent sci-fi books that focus heavily on the characters. It can be fun fluff or deal heavily with sociological or political themes. I don't care. As long as it focuses primarily on people instead of the science or technology I'll probably enjoy it. Ender's Game is the perfect example of what I'm looking for in a book.
