I just received my copies of the two SpaceX/others books that came out today. The Space Barons (Elon Musk, Jeff Bezos, and the quest to colonize the cosmos): https://www.amazon.com/gp/product/1610398297 Rocket Billionaires (Elon Musk, Jeff Bezos, and the new space race): https://www.amazon.com/gp/product/1328662233 People might be more familiar with the first book as the author works for The Washington Post and excerpts have been written promoting the book. So, of course, I 'm going to start reading the second book first. Actually, reading the author bios, the second book seems to have a better pedigree and has a chance to be better researched. When I get through the books I'll post my thoughts.
