The year was 1975, and at age 16, young Keri was desperate to strike out on her own. However, as listeners of the first three volumes of this series will know, her childhood was hardly the loving, supportive, preparatory period it should have been. Should it really be any surprise then, after such a traumatic baptism into life, that her first foray into the adult world was hardly an unmitigated success? But just when she thought she'd finally left her demons behind, she found herself at the mercy of unsavoury characters yet again - and this time, without anyone to turn to...

From the outside, there was no reason to suspect the family life of young schoolchild Keri was anything but unremarkable. Two loving parents, a backdrop of 1960s Britain; life had provided for her, at least with the riches of modesty. Keri herself however, would often confound teachers with her erratic behaviour, which was at best sullen and withdrawn; at worst violently disruptive. When challenged, she would only exacerbate her growing reputation as a fantasist; weaving terrible tales about the "abuse" she was suffering at the hands of her very creators.

Stephen Smith is the boy who did not exist. Born out of wedlock in the early 1960s, Steve's parents - both devout Catholics - had felt so 'shamed' by their son's illegitimate birth that they hid him away from the world by locking him in the cellar...for 13 years. Apart from a few admissions to hospital as a result of his 'imprisonment', Steve remained in the coal cellar of the family home where he was deprived of daylight, his childhood, school and human contact until he'd reached his teenage years.

Fourteen-year-old Shazia has been taken into care after a conversation at school leads her teacher to suspect that the teenager's family are planning to send her to Pakistan for an arranged marriage. To her family's fury, Shazia is sent to live with foster carer Maggie Hartley whilst social services investigate. But with Shazia denying everything and social services unable to find any evidence to support the teacher's fears, Shazia is allowed to return home. But a few weeks later, Maggie is woken up in the middle of the night by a phone call from a terrified Shazia, who has managed to escape the family home through a window. 

Being a teenager isn't easy. Even kids who grow up in happy, loving households encounter all manner of problems during adolescence. But children who were abused, raped, bullied, mistreated or neglected during their earliest years, face the transition at an even greater disadvantage. For they not only come completely ill-prepared, but also badly scarred, and often still licking the wounds from their childhoods.

In this much-publicised third volume, Kat recounts her early-mid teen years; no longer a small child, but a girl on the cusp of adolescence. Still traumatized by her early experiences, but not entirely without that sense of vague hope that is the inalienable property of youth. Now at Duncroft Approved School for “emotionally disturbed girls”, her life had come to resemble that of a prisoner; a good day was a bad one and a bad day was horrific.

Growing up in a quiet, middle-class suburb outside of Amsterdam, childhood best friends Anna and Olivia had their whole lives ahead of them. But every parent's worst nightmare came true when the teenagers fell in with the wrong crowd. Eleven years their senior, Ryan was charming and good-looking - and Anna and Oliva easy prey. Blind to his grooming, the girls were soon trapped in a terrifying cycle of sexual and physical abuse.    

Natalie Queiroz was eight months pregnant when she was stabbed by her partner in the most vicious attack imaginable. In the space of nine minutes, and in broad daylight, Natalie was stabbed 24 times with a carving knife. She suffered horrific wounds to her lungs, liver, stomach and uterus, whilst the knife missed her baby by a margin of two millimetres, before the arteries in her wrists were methodically severed by the attacker she finally realised was her partner. After heroic intervention by passers-by and police, the attack was brought to an end, but her ordeal was not over.

Casey Watson is back, doing the job she does best - rolling up her sleeves and fostering the children who, on first meeting, seem like hopeless cases. But when she meets Miller and discovers the truth about his disturbing childhood, even Casey begins to doubt if this child will ever be able to accept love. Found naked and alone on a railway track, Miller was just five when he was first admitted into the care system. 

By the age of 13, vulnerable Sheffield teenager Samantha Owens had fallen through the cracks in the care system. Bounced around numerous foster carers after her home life became too chaotic, Samantha thought she had found a friend in the streetwise Amanda Spencer. The older girl bought her clothes, styled her hair and found her places to stay. Samantha's welfare was the last thing on Spencer's mind, however, as in reality she was grooming the young girl for exploitation of the worst possible kind.

Having recently lost his mum to cancer, when eight-year-old Tom comes to live with Maggie, he is scared and alone. Tom has been taken into care following concerns from his teachers about his dad Mark's ability to cope as a single parent following the death of his wife.
