Rose and Windy have been coming to the same beach every summer for years. Rose is a bit older and is starting to change into a young woman while Windy is still a girl. They have a sisterly relationship and enjoy their summers together. Rose is experiencing family strife and trying to figure out who she is as a young woman. Windy is still happy-go-lucky.
This graphic novel is based in summer fun, but there are a lot of serious issues going on here. Rose's parents are dealing with infertility and loss. The young man who works at the local store may have gotten his girlfriend pregnant. The older kids curse and talk about sex. This is not a story for younger readers. I think the appropriate age depends on your individual beliefs, but I would say high school.
I found the hyperness of Windy a bit irritating and I didn't love the book. But I can see that it is well-written and will appeal to many teens and young adults. I read this book for my Young Adult literature class. :)
