This is such a - I don't know how to describe this book! It doesn't seem to fit in any word. I can just say it's sad, but happy, plain, but special. Sad because the ending is not quite as how we imagine it, but if you are engaged in the book, you will see a unique happiness of friendship and more, family. And that is a plain story about a girl, Hattie, in Montana's story. Only, the name of the book "Hattie big sky" will help you find why and how the story is so special.
