Nelson Denis is an attorney, writer, film director, and former New York State Assemblyman. His new book is based on recently declassified FBI files, congressional testimony, oral histories, personal interviews and eyewitness accounts. It covers the Puerto Rican Nationalist Party Revolts of the 1950s, a series of coordinated armed protests for the independence of Puerto Rico led by the president of the Puerto Rican Nationalist Party, Don Pedro Albizu Campos.

The book also documents how the U.S. Army bombarded two towns and deployed thousands of troops in order to stop the uprising – the only time in history that the U.S. government intentionally bombed U.S. citizens.
