I just finished rereading Ender's Game, so now I'm working my way through the saga, and I also picked up Ender's Shadow yesterday, as well. I'm also nearly through with The Cartoon History of the Universe, Part 3 (Very interesting series, I recommend them for anyone who wants a walk through history told in an extremely lighthearted manner), and I'll be starting with ...Of the Modern World, Part 1 soon.
And then I also picked up The Culture of Fear and The Spartacus War. You know, for some light bedtime reading.
