It’s Casey McQuiston, of course this book gets five stars. 

This book was so much fun. A beautiful ya romcom, full of teenage drama, idiocy, passion, love and friendship. The cast of characters was wonderful. Everyone was so interesting and the whole group was diverse and fun. There were just a tad bit too many characters because I did loose track of them sometimes. 
The representation in this was wonderful. Queer found family, or in this case a queer friend group, just makes me unbelievably happy. And the book kept getting queerer (is that a word? it is now). Watching them grow and become more confident in who they were was wonderful to read.
