McDonald is a contributing editor at Fortune magazine and the New York Observer; he has also written for Vanity Fair, New York, Esquire, Business Week, GQ, WIRED, and other publications. His first book, Last Man Standing (2009), delved into the 2008 financial crisis through a profile of Jamie Dimon, CEO of JP Morgan Chase. In his new one, he examines one of the worldÂ’s most influential companies that you probably never heard of, the consulting firm of McKinsey & Company. Ranked among the top-rated consulting organizations for decades, McKinsey & Company has been a top-brass advisor to most of the Fortune 500 corporations at one time or another, though its client list has always been a well-guarded secret. This is a company that has prided itself as having the highest standards in the industry yet has contributed behind the scenes to severe cost cutting and downsizing, acted as enablers to the Enron and General Motors bankruptcies, and seen a former CEO hauled off to jail for insider trading. McDonaldÂ’s reporting reveals how and why this Teflon firm has continued to thrive through the years. --David Siegfried
