It's a decent biography. I am not saying Elon's life is less illustrious then it is portrayed in the book but since most of his projects started delivering late and book was completed in 2014, much of the success story, his upcoming projects, are definitely not there. Secondly, this biography appears to be an outsider's take on Elon's life and it feels that his involvement, sharing of his thought process and his life has been very limited. It is generally a good book if you want to go through how he started and what he has done but if you want to go in to his mind, how he did what he is doing and what he is planning to do? then may be you will feel a little disappointed. I think a more exhaustive work might be required say in next five to ten years when his projects actually start delivering commercially as well as whatever his world view is about interplanetary travels and sustainable energy.
