Amazon Unbound by Brad Stone

In Amazon Unbound, Brad Stone presents a deeply reported, vividly drawn portrait of how a retail upstart became one of the most powerful and feared entities in the global economy. Stone also probes the evolution of Bezos himself—who started as a geeky technologist totally devoted to building Amazon, but who transformed to become a fit, disciplined billionaire with global ambitions; who ruled Amazon with an iron fist, even as he found his personal life splashed over the tabloids.
