I finished the book almost in one setting. It is a worthy companion to the best of any from the Apollo Era. The author tells the story exactly as it was with out any of the hype but all of the emotional gutwrenching trials, failures and amazing highs of successes that happened in the early days of SpaceX. It really seeks to tell the whole story of SpaceX, Elon included, but not the whole focus. If you are at all interested in space, industry disruption or understanding how what makes SpaceX so unique and hard to replicate, this is the book to read.
