This book caught me from first look. Scott Kelly who is an Engineer, Retired Astronaut, U.S. Navy Captain and four space flights. I can't wait to read more of this book as he is one of America's true hero's. I love his passion for hope, kindness and taking a part in taking care of our planet. I can only imagine the sacrifice he made to spend an entire year in space and the toll it took on him emotionally. His accomplishments in life are amazing.
