One afternoon after Kelly Thorndike moved back home to Baltimore, an African-American man calls to him. To Kelly?s shock, he identifies himself as Martin, one of Kelly?s high school friends ? skinny, white, and Jewish when he disappeared nearly twenty years ago. The story is astonishing: after years of immersing himself in black culture, Martin had ?racial reassignment surgery? and has been living a new life. Now he?s ready to sell it to the world.
