Historical fiction for ages 8-12, I feel the upper end of those ages are a good fit for this book. Clem goes from 9-11 or 12 years old in this book, and the emotion, growth, and historical references may be harder for the 3rd and 4th graders to grasp. It is part of a trilogy, but the books are companions rather than sequential. I did not read the other two, and had no issues. I enjoyed this book very much, and it is pretty low-key, without a lot of action or happenings. It was just engrossing and I always wanted to keep reading. There is grief, and how this family handled it before kids could just go talk to a counselor (or adults--but they wouldn't have been able to afford it), family dynamics, fear, friendships and lack thereof, bullying, being yourself/growing up, and racism. The racism in the book is mostly systemic, and explained well. The acts of racism are usually microaggressions, such as calling the maid "Cece", rather than Mrs. Thurber. These are explained, too, so that the young reader will understand the problem. Most of the historical references are not explained, so children may want to look up some of the names that I knew without a problem. (Lena Horn, Joe Lewis, etc.) This book has a feel-good ending, and I would have loved a Dickensian epilogue explaining what happened in their futures. Excellent author's note.
