The message is that each man's choices impacted how another's life would be, creating a chain of events that eventually saved billions of lives.
Written as a children's book, the author uses easy to understand language and beautiful illustration to tell the stories of each of these men. I found gaps in the logistics how each man changed history yet, when written as a children's book, I enjoyed the message much more. Idealistically speaking, a child will begin to believe that by making good choices, s/he may impact another.
My 5 year old son enjoyed it, although he was a little confused with the relationships as I read it to him. He liked it quite a bit and I like the message, although incomplete to me.
I received this book free from Thomas Nelson Publishers as part of their BookSneeze.com
