Query: This is a real life story, sad, but totally believable.

In one way, I found this book sad and depressing, but in another way, uplifting because of how the human spirit can endure and even thrive under terrible circumstances. I thought it was a fabulous story and could not put it down. Made me aware of how many children like Astrid are out there, just trying to survive, and hopefully, succeeding.
