I think that the books are not as - well - as well-written as they would have been if they'd been targeted to an older audience, and I wish that they're been targeted to that older audience. (The older, the better.) But for all that they were fun, and anyone who uses footnotes well without looking like a Pratchett-clone is a good person in my book.

More than that, I think I wish I had the story that comes after Ptolemy's Gate. There's some very interesting things happening then, and a potentially very interesting YA novel in Kitty or whatever her name is, living the way she must after aging as she did, and still managing a post-revolution society.
