Susan Faludi has made a career of examining the politics of gender. Her first book, “Backlash: The Undeclared War against American Women,” was a rallying cry for feminists in the early ‘90s. She followed that up with an examination of men in American society. Now the Pulitzer Prize-winning author and journalist has turned her investigative pen on herself, her father and the politics of family. In her new book, “In the Darkroom,” Faludi reconnects with her estranged father after he becomes a she. Steven Faludi had gender reassignment surgery when he was in his 70s and became Stephanie Faludi. Susan spends 10 years with her father, trying to understand her and the bigger issues of how gender, religion and identity shape a family and a society.
