A reader asks:

I'm interested in finding some good libertarian fiction for my (almost) twelve year-old -- "libertarian" because I'd like her to get some exposure to those ideas, and "fiction" because that's what interests her. The problem is that I haven't read a lot of libertarian fiction, and I started when I was much older. Most of the stuff I'm familiar with has some fairly adult content.

Naturally, different people have different views about what's suitable for 12-year-olds, or for that matter what 12-year-olds are likely to find interesting. But even given this, I expect that many readers would like to hear suggestions on this score. Please post your recommendations in the comments, with whatever details you might like.
