The Sword of Kaigen

It's so difficult to put to words all that I feel about this book. It definitely defied all my expectations. Being a mother of a 8yo and 4yo boys, I almost wanted to just stop reading the book altogether at some points and even took a few days' break in reading at some point, because it was too heartwrenching for me.
But in some weird way it was worth it. Almost all of my questions that I had in the first part of the book were answered in the end. And it feels right.
