Elon Musk (New York City: Ecco, 2015)

If you have a narrow definition of success, Elon Musk is one of the most successful entrepreneurs of all time. However, I see this biography as more of a cautionary tale. In his drive to win, Musk sacrifices friends, business associates, and even his family to get what he wants. His life (so far) is a living example of what happens when you value projects more than people.
