that's, actually, a really good theory. I realized, when I was reading the earlier books, that some of the terms used were the names of later books, like, when I first read book 1, book 3 was already out, and when they talked about the everblaze, I was like, "oh, that's the name of the 3rd book!", and then in the 2nd book when they talk about the lodestar mirror, and that's the 5th book, and they talk about sophie being project moonlark a lot, so that's a very likely theory.
