In How to Hide an Empire, Daniel Immerwahr tells the fascinating story of the United States outside the United States. In crackling, fast-paced prose, he reveals forgotten episodes that cast American history in a new light. We travel to the Guano Islands, where prospectors collected one of the nineteenth century’s most valuable commodities, and the Philippines, site of the most destructive event on U.S. soil. In Puerto Rico, Immerwahr shows how U.S. doctors conducted grisly experiments they would never have conducted on the mainland and charts the emergence of independence fighters who would shoot up the U.S. Congress.
