"...[An] engrossing account of the clash between these two giants. This is no bird’s-eye view: The author knows both companies well, and he is not afraid of plumbing the details of their attempts to meet their customers online. While retailing is his nominal topic, Mr. Del Rey’s real subject is the difficulty of driving change in a large organization. His book will fascinate anybody who is trying to run one.” — Wall Street Journal
