1) I have to suggest this because it's always great to look into someone's mind, and I can't think of a more interesting mind than his.
2) A lot of your books were based on gaining a knowledge of Earth, but if we're to look to the future, we should grasp space as well.
3) This is my current favorite book because it's an incredibly well written mystery that I had the pleasure of enjoying a few years back when I got it from the library. Since then, I've devoured the entire series, and can not suggest them enough for fans of mysteries.
4) I would love this because I could use a good laugh, and I'm perfectly okay with it being used.
