William Morgan, a tough-talking ex-paratrooper, stunned family and friends when in 1957 he left Ohio to join freedom fighters in the mountains of Cuba. He led one band of guerrillas, and Che Guevara another, and together they swept through the country, ultimately forcing corrupt dictator Fulgencio Batista from power. Drawing on declassified FBI, CIA, and Army intelligence records as well as diaries, Pulitzer Prize-winning authors Michael Sallah and Mitch Weiss skillfully reveal the inner workings of the Cuban Revolution while detailing the incredible love story of a rebel nurse and an American street hero who left their mark on history.
