Query: So So So sad...

This book was so engaging! I literally was a wreck and had tears streaming down my face when I finished it! I was drained emotionally. The only criticism I have for this book is that it is written all in dialogue without any narration. By the end, I was used to it, but at first it was a little difficult to follow along. ... It definitely sticks with you. Sharon Draper's writing is wonderful!
