But when Sylvie's end-of-summer birthday party becomes the end of their friendship, Eleni can't picture starting middle school without her BFF by her side. She can't picture anything without her BFF--especially the looming school overnight. Who will she even room with?

So before the big overnight, Eleni sets out on a mission: to figure out where her friendships went wrong, what's wrong with her, and what makes a good friend. But if she's totally honest, there's only one real goal: to win back Sylvie Bank!
