I find that reading old books is a little like traveling in time. I sometimes pick up a little history in my fiction, but I also learn how our view of that history has changed over the years, and when I see prejudices in older books, I am reminded to try to keep a closer eye on my own.
...It’s a pattern that I like for the whole series – you read one story, you receive information, then you get a slightly different story – because I’m a re-reader. Books I like I read again, and again, and again, and again, and I want to write for the people who read again.

I think a good book is a good book forever. I don’t think they get less good because times change.
And then we get to YA literature. The great truth teller to teens everywhere. And sometimes we’re still lying. That’s why we have those fantasies set in pseudo pre-industrial and feudal periods, but still enlightened enough to have a woman warrior. They may be well-intentioned lies, but these are not young children. They might not be sophisticated enough to see through the lies, but give them the truth, believe that they are ready for it or they wouldn’t be reading the book.
