"Empowering . . . sweepingly ambitious . . . . Rosenberg's case studies are as different as they are fascinating . . . A brilliant book." —Abraham Verghese, Newsweek A winner of the National Book Award and the Pulitzer Prize, Tina Rosenberg has spent her career tackling some of the world’s hardest problems.
