I enjoyed reading this book a lot. Her way of writing the high school experience feels very real and intense. It reminded me a lot of my own high school days, even though we only shared a few similarities. I loved having such an observant main character, and the comments she made about human behavior often closely aligned to what I believe now and also what I believed when I was younger. I like how the book was unapologetically centered around only her time in high school. Minor interactions were taken very seriously, and it worked because when you are that age those interactions really do feel like life or death. I think the commentary on race and class was insightful if a little open ended. Something that bothered me was the reliance on stereotypes for minorities (most of her black characters playing basketball, a black character stealing, an Asian character obsessed with grades), although I do believe she was attempting to address these stereotypes and show the ways in which people defy them. I think it could have been handled better but it does seem like a good starting point for a discussion. 
Favorite quotes: 
“It is, of course, a mark of my youth at the time that to try too hard struck me as so sad, as if the world were not full of many greater sorrows.” 
“The big occurrences in life, the serious ones, have for me always been nearly impossible to recognize because they never feel big or serious. In the moment, you have to pee, or your arm itches, or what people are saying to you strikes you as melodramatic or sentimental, and it’s hard not to smirk. You have a sense of what this type of situation should be like- for one thing, all-consuming- and this isn’t it. But then you look back, and it was it; it did happen.”
