30 Best Middle-Grade Books About Sisters

Don’t you just love middle-grade books about sisters? I know I do! Maybe because I don’t have a biological sister myself, I really enjoy reading about sister relationships — the good, the sweet, and the messy! (Sidebar: If you want an adult fiction recommendation about sisters, check out this book!) Today, though, we’re talking the best middle-grade books about sisters! I know that many parents and teachers prefer books that model positive sibling relationships (less backbiting, more love) and I’m all for that as well. Most of the books on this list feature sweet sister relationships, while the rest feature difficult relationships that significantly improve by the end of the story.

As life can be, a few of these stories are a bit sad and feature the death of a sister, or a sister with a serious illness. But many others are adventure-filled or feature families coping with financial insecurity, the end of a marriage, and other challenges. Overall, though, I’ve only chosen books with a focus on the relationship between two or more sisters. Twins, big sisters, little sisters, close in age, far apart — it’s a sister party!
