Helen grew up in a pit village in Tyneside in the post-war years, with her gran, aunties and uncles living nearby. She felt safe with them, but they could not protect her from her neglectful mother and violent father. Behind closed doors, she suffered years of abuse. Sometimes she talked to an imaginary sister, the only one who understood her pain. Jenny was adopted at six weeks and grew up in Newcastle. An only child, she knew she was loved, and with the support of her parents she went on to become a golfing champion, but still she felt that something was missing. Neither woman knew of the other's existence until, in her fifties, Jenny went looking for her birth family and found her sister Helen. Together they searched for the truth about Jenny's birth - and uncovered a legacy of secrets that overturned everything Helen thought she knew about her family. Happily, they also discovered that they were not just sisters, they were twins.
