I feel like I'm going to sit with this book in my mind for a very long time and never actually understand it. And there's nothing wrong with that.
I wouldn't recommend this for plot readers. Not a lot happens in this book, and the structure is weird. It's all about the characters, specifically the lead. You're in her head dealing with her confusion, and it's pretty great.
Also, for me, the depiction of stressful, exclusive, small college pressure was just very, very well done. I've known people that handled college like almost every one of these characters. It was a highlight to read for sure.
