There's a lot to like here, but story-wise it does retread a lot of ground we've honestly seen before. I think in the notes he mentioned he wanted to sew up a few plotholes once he started writing it, but honestly, the last 25% of the book probably could have been a short by itself. Zoe is an interesting, fun character to follow, though. Mostly what makes this book weaker is that it's retreading the same water we just swam out of.
