Book excerpt: Fall to Pieces is a beautifully written, visceral, roller coaster ride inside bipolar disorder, rock ’n’ roll, celebrity culture, and the world of modeling. Mary Forsberg Weiland, ex-wife of the late Scott Weiland, front man for Stone Temple Pilots and Velvet Revolver, tells a harrowing true story of depression, drug addiction, and mental illness with candor and, often, humor. Co-written with veteran journalist Larkin Warren, Fall to Pieces is a blistering, eye-opening memoir of Hollywood meltdown in the bestselling vein of Tatum O’Neal’s A Paper Life and Valerie Bertinelli’s Losing It.
