It's an easy and fun read and Ashlee did a good job in not falling to temptation of deep diving into technical challenges Musk and team would have faced during their sojourn. The book gives good insight about persona of Musk however the writing leans too heavily on idolatry, almost making him super-human or real-life version of Tony Stark. May be Elon wouldn't have approved of a more realistic version of the biography.
