A thoughtful glimpse into the childhood of Norma Jeane Mortenson and how it shaped her into the iconic Marilyn Monroe for the 100th anniversary of her birth. At the fragile intersection of myth and memory stands a girl—often eclipsed by the legend she became. The Girl Who Would Be Marilyn Monroe dares to strip away the satin, the spotlight, the studio-invented shine, to reveal the tender child beneath: a girl marked not by fame but by longing. Longing for love, for safety, for the kind of permanence the world never offered her. This is not simply another biography. It is a resurrection. A candlelit portrait drawn from decades of first-hand research and rare interviews with those who knew her—not only Marilyn the icon, but Norma Jeane the girl. Tony Castro draws on intimate conversations with famed entertainment writer James Bacon and Marilyn’s close friends, such as Frank Sinatra, actresses Susan Strasberg and Mamie Van Doren, actor and The Misfits co-star Eli Wallach, ex-husband Joe DiMaggio, and child star-turned-Hollywood raconteur Skip E. Lowe. They offer unparalleled access into Marilyn’s earliest, most hidden self. These are stories shared not as interviews but as confidences—shaped by the trust of friendship. And herein lies the soul of this work: a new and intimate rendering of the Marilyn we rarely allow ourselves to see. Through these private recollections, we hear her voice—not the whispery affectation of the screen siren, but the real girl’s voice, unvarnished, aching, often uncertain. What emerges is not the blonde bombshell, but the child whispering to a mirror, trying on hope like a costume. This is, at last, the story of Norma Jeane.
