In a riveting dramatic narrative based on over 200 interviews, Wall Street Journal senior writer Monica Langley tells the inside story of how a rough-edged kid from Brooklyn battled the venerable old guard on his way to becoming a billionaire, shaping the future of financial services in America, and as the head of Citigroup, building the largest financial empire in the world. Langley explores the inner workings of power at the highest levels of business and also revels the unorthodox management style and surprisingly simple principles that have made Weill a legend on Wall Street.
