Things I liked:
- the acknowledgement of both North Carolina and New York having broad differences in where you can live (I was born in Rochester, New York, which is more like Ohio than it is NYC, and I live in central North Carolina but have been on trips to both the mountains and beaches and yeah, you get a bit of everything here)
- astronomy geekery
- the raw, honest portrayal of complicated relationships

Things I did NOT like:
-

Spoiler

how Maia first found out that Chris is trans

I went to a panel with Amber Smith before buying this book, and she gave the disclaimer that she wasn't trans, her wife isn't trans, and she did a LOT of research to get this book right, but... One of the number one no-gos when writing trans characters is having them be outed because someone saw them undressing (beaten only by having them being killed, I think). That scene... Just made me sick. It's otherwise a very fantastic book, but the scene where Maia watches Chris get changed...
You don't do that to trans characters. You just don't.
