For over 20 years, Joanne Lee's mother kept the remains of three newborn babies hidden in her wardrobe. For the first time since exposing her mother's crimes, Joanne breaks her silence over her family's horrific ordeal. Growing up, Joanne suffered at the hands of a violent boyfriend and controlling relatives, as her mother lapsed into a downward spiral following the break-up of her marriage. But the consequences of her mother's lifestyle turned out to be worse than Joanne could ever have imagined. She already knew about the baby buried in a shallow makeshift grave next to the family plot. But when Joanne came across a red plastic bin in her mother's wardrobe in 2009, she realized that the family home held an even more sinister secret. In Silent Sisters, Joanne will tell her story, detailing her struggle to understand her mother, to piece together the truth and give the four babies the proper burial they deserve.
