Potential spoilers ahead: I really like the way that this book is structured by splitting the three parts into three different point of views (first, second, and third person). I think this was a very creative approach to the storytelling and the book is definitely worth a read to experience that.
However, there is some biphobic ideologies in the book. Some of this biphobia was internalized by the main character and some was externalized by the main character's lesbian friend group. As a person who identifies as bisexual and has experienced biphobia in my life these passages were incredibly upsetting to read.
