Poppy's twin sister Lola has disappeared and neither of their parents have made an effort to find out where she's gone. So Poppy has decided to send letters to Lola and send them to a location she remembers Lola using. Poppy also spends time with her friends and girlfriend Juniper. I really liked this book even when there were pop culture references that I'm unfamiliar with. The romance between Poppy and Juniper is so sweet and adorable. The letters Poppy writes to Lola describes both happy and sad moments as well as the events that led to Lola deciding to leave. It is a good idea to check content warnings for this book before reading it.
