This is a really beautiful story about the tipping point between childhood and adolescence. This transition is shown in the differences between Windy and Rose. Windy is still full of childish exuberance, whereas Rose is more moody and quiet. As I read, I couldn't help wondering how their summers would pan out in the coming years; whether Windy and Rose would stay close or if they would drift apart.
I know other reviewers haven't got on with this book because they felt it didn't have enough plot going on. It's true - there's no huge story arc, no twists and turns, so if this is your thing then this book might not be the one for you. The story is low-key, it just drifts quietly along with beautiful artwork telling the tale of the summer and giving background behind Rose's parents' fighting (which actually does get a bit of resolution). The story ends at the end of the summer, and that's it.
I think this will especially appeal to anyone who goes on holiday to the same place with their family every year. this book reminded me a lot of The Summer I Turned Pretty by Jenny Han as the author and illustrator sum up perfectly that feeling of summer nostalgia and pleasant boredom of doing the same thing every year.
