Maybe this article is filler, but Eric Berger is a well-respected veteran space journalist, and generally his articles on Ars Technica are great.
He's just released a book on the early days of SpaceX [1] that appears to be the definitive account, according to the early reviews.
I'm not associated, but I have been wanting to read his book and am happy it has finally been released! :)
