Book excerpt: Traditional walking tours of New York enshrine the wealthy and the war heroes. Rarely seen are those buried in their wake - those who fought the power, pushing for a better world. In this exciting new guide, Bruce Kayton leads us to differnt kinds of monuments, offering readers a history of class struggles, labour movements and civil rights battles, with such sites as Emma Goldman's home in the East Village, Langston Hughes's house in Harlem and the site of Margaret Sanger's first birth control clinic. A new perspective on the history of New York and American radicalism.
