The “haunting” (New York Times Book Review) story of a virus that triggered the worst pandemic of the 20th century
  The flu pandemic of 1918-1920 was one of the greatest human disasters of all time. It infected a third of the people on Earth—from the poorest immigrants of New York City to the king of Spain, Franz Kafka, Mahatma Gandhi, and Woodrow Wilson. But despite a death toll of between 50 and 100 million people, it exists in our memory as an afterthought to World War I.
 
In this gripping narrative history, Laura Spinney traces the overlooked pandemic to reveal how the virus traveled across the globe, exposing mankind’s vulnerability and putting our ingenuity to the test. Drawing on the latest research in history, virology, epidemiology, psychology, and economics, Pale Rider masterfully recounts the little-known catastrophe that forever changed humanity.
