Phoebe loves her pet fish, Betty #2 (named after Betty #1, may she rest in peace), making lists, and her best friend Sage. But when Camille, a tall French girl, arrives at school with unusual lunches, Phoebe can't seem to think about anything else, including her friendship with Sage.

Thanks to Camille, Phoebe discovers goat cheese, butter lettuce, and cilantro (although she's convinced that's not a real word). She's determined to get invited to her new friend's house for dinner to see what other mysterious food Camille eats. But what about Sage? Can Phoebe make a new friend and keep an old one?
