When I was in middle school. I read this series of books about a group of friends who worked in a coffee shop (after school or something, they were about 14, I think...). There was a bunch of those books, and each one was from a different girl's perspective. Anyone have an idea which books I'm talking about? For some reason, they came to my mind and I have to find out who wrote them, even though I don't remember much. Lol. Help?
