Our guest is Dorothy Wickenden, an author and editor at The New Yorker Magazine. She tells us about her fascinating new book, which explores various interlinked facets of American history, including abolition, the Underground Railroad, the early women's rights movement, and the Civil War. As the noted Yale historian David W. Blight has written of this book: "As a revolutionary, Harriet Tubman made many allies, none more important than her Auburn, New York, neighbors Martha Wright and Frances Seward. Wright, a middle-class Quaker, and Seward, the wealthy wife of a famous statesman, learned their activism from the abolition and women's rights movements that surrounded them, as well as from Tubman's incomparable example. This is a unique, lyrically written, exhaustively researched triple-biography of epic proportions about three women, mothers and organizers all, woven into a single narrative about their activist struggles before and during the Civil War. Their lives burst from these pages, as do the crusades that began the liberation of African Americans and women across the nineteenth century."
