NEW YORK (AP) - As Marcia Brady on "The Brady Bunch," Maureen McCormick projected an image of the wholesome girl next door. But off camera, she spiraled downward into drug addiction and depression.

Now 52, McCormick writes about her struggles in a new memoir, "Surviving Marcia Brady and Finding My True Voice," hitting stores Tuesday. She discusses her romance with TV sibling Barry Williams, her dates with Michael Jackson and Steve Martin, cocaine binges and parties at the Playboy Mansion and the home of Sammy Davis Jr., an unwanted pregnancy and trading sex for drugs.
