Mahoney authentically captures the universal indignities of middle school, the challenges of self-discovery, and the joy of making true friends. --Publishers Weekly, Starred Review

Dear Lou,
You've been asking and asking about what middle school is like, but I just thought they were annoying-younger-sister questions. Even though I am almost done with my first year, I can still remember when I thought middle school was a mystery, so I'll try to give you a leg up. I know middle school is a lot to figure out. But since I still haven't worked it all out yet, I'm happy to help as much as I can. That's what big sisters are for.
Love, Gus
