The death of the living embodiment of a global megabrand - Steve Jobs left a gaping void at one of the most innovative companies of all time. It seemed impossible for anyone to supplant the avatar - especially not intensely private executive Tim Cook, who many thought of as Apple's "operations drone." But seven years later, as journalist Leander Kahney reveals in this definitive book, Apple’s stock nearly tripled, making it the world's first trillion dollar company. Pushing hard into renewable energy, labor and environmentally-friendly supply chains, user privacy, and highly-recyclable products, Cook is leading Apple to a new era of success. Drawing on access with several Apple insiders, Kahney tells the inspiring story of how one man attempted to replace someone irreplaceable, and - through strong and humane leadership, intelligent supply chain, and a commitment to his values - succeeded more than anyone had thought possible.
