Twilight Children:

From the author of the phenomenal Sunday Times bestsellers ‘One Child’ and ‘Ghost Girl’, comes a startling and poignant memoir of three people's victimisation and abuse – and their heartbreaking but ultimately successful steps to recovery, with the help of Torey Hayden, an extraordinary teacher.
Two children trapped in a prison of silence and a woman suffering in the twilight of her years – these are the cases that would test the extraordinary courage, compassion and skill of Torey Hayden and ultimately reaffirm her faith in the indomitable strength of the human spirit.
While working in the children’s psychiatric ward of a large hospital, Torey was introduced to seven-year-old Cassandra, a child who had been kidnapped by her father and was found dirty, starving and picking though rubbish bins to survive. She refused to speak, so Torey could only imagine what she’d been through. Drake, by contrast, was a charismatic four-year-old who managed to participate fully in his pre-school class without uttering a single word. Then, there was Gerda, eighty-two, who had suffered a massive stroke and was unwilling to engage in conversation with anyone. Although Torey had never worked with adults, she agreed to help when all other efforts had failed.
