Marcia Brady had it all - style, looks, boys, brains and talent. No wonder Jan was jealous! Young woman across the generations cheered on as Marcia ran for student president and took her drivers test. We swooned when she got the lead role in Romeo and Juliet and sported those groovy ponchos and platform shoes. We understood when Marcia suffered through braces and a slight case of acne. We cried when she broke her nose, lost dates all because of her brothers and even lost the attic to Greg. What viewers didn't know about the always sunny, perfect Marcia Brady was that off-screen, the real little girl, Maureen McCormick, was living a very different and not-so-wonderful life. She discloses the devastating effects of a dark secret her mother tried to keep until near the end of her life, and also how that affected her relationship with her parents and five siblings, including a mentally disabled brother with whom she was very close.
