I will echo the words of other reviewers of this book: it does take quite a bit of time to really get into it, but it's so worth it. There's no shortage of thoughtful character development and world building going on throughout this whole book and it's honestly ended up being my favorite in the series. There's so much interesting detail this book adds to the series, even if YA isn't your thing, if you ever read the original trilogy you should probably pick this one up.
