James Tiptree, Jr., burst onto the science fiction scene in the late 1960s with a series of hard-edged, provocative stories. He redefined the genre with such classics as Houston, Houston, Do You Read? and The Women Men Don't See. For nearly ten years he wrote and carried on intimate correspondences with other writers--Philip K. Dick, Harlan Ellison, and Ursula K. Le Guin, though none of them knew his true identity. Then the cover was blown on his alter ego: he was actually a sixty-one-year-old woman named Alice Bradley Sheldon. A feminist, she took a male name as a joke--and found the voice to write her stories. Based on extensive research, exclusive interviews, and full access to Alice Sheldon's papers, Julie Phillips has penned a biography of a profoundly original writer and a woman far ahead of her time.
