This story began before I was born, when my father, Ellis P. Steinberg, and uncle Bernard Abraham worked on the secret undertaking that developed the first atomic bombs. These later were dropped over Hiroshima and Nagasaki. It was not only my extended nuclear family that experienced and was affected by growing up at this time in history, but a whole generation of other children raised in the shadow of the bomb who had stories to tell. The result is this book--part memoir, part discussions with siblings and cousins, and part interviews with a dozen others who had a parent who worked on the Project.
