Well known as a tyrant, the women's accounts have helped to paint Gaddafi - or Papa Muammar as he liked to be called - in an even more monstrous light, outing him as a repugnant sadist for whom rape was a daily activity.
One girl describes how she was forced to wear lacy underwear and watch porn films. She added that Gaddafi had 'needed' several girls every day.He also raped boys, sometimes in Soraya's presence.
The book also reveals how Gaddafi's sex slave victims are still suffering after being rejected by their families for having sex when they were not married.
Soraya says she lives in fear of her brothers, who may want to kill her to 'wipe away the shame'.
Female visitors were routinely subjected to blood tests by Gaddafi's nurses to make sure they were disease free in case he wanted to have sex with them.
Marie Colvin, the Sunday Times journalist killed in Syria last year, reported that a nurse had approached her with a needle when she was in Tripoli to interview Gaddafi. She declined to give blood.
When he was alive, Gaddafi was always surrounded by uniformed women, but far from being security guards they were his sexual playthings kept at the dictator's beck and call, according to the book.
It also describes how Gaddafi kept a secret flat at Tripoli University to 'entertain students'.
Cojean, a reporter for French newspaper Le Monde, said the accounts is the book had been one of her 'most painful investigations'.
In an interview with France24, she said: 'For Gaddafi, rape was a weapon...a way of dominating others - women, obviously, because it was easy, but also men, by possessing their wives and daughters.'
