In 2006, the Wall Street pioneer and philanthropist Ray Chambers flicked through some holiday snapshots taken by his friend, development economist Jeff Sachs, and remarked on the placid beauty of a group of sleeping Malawian children. “They’re not sleeping,” Sachs told him. “They’re in malarial comas. A few days later, they were all dead.” Chambers had long avoided the public eye, but this moment sparked his determination to coordinate an unprecedented, worldwide effort to eradicate a disease that has haunted humanity since before the advent of medicine. Award-winning journalist Alex Perry obtained unique access to Chambers, now the UN Special Envoy for Malaria. In this book, Perry weaves together science and history with on-the-ground reporting and a riveting exposé of the workings of humanitarian aid to document Chambers’ campaign.
