Chris Hadfield's book shows us our home - our city, country, continent, our whole planet - from a unique perspective. The millions of us who followed Chris's Twitter feed from the ISS thought we knew what we were looking at when we saw his photos. This photo documentary shows us we didn't. We caught the beauty but missed the meaning. Curated from images never before shared, Chris's big picture reveals why our planet looks the way it does and why we live where we do.
