Virginia Giuffre's posthumous book has revealed her grief at not being allowed to testify against Ghislaine Maxwell because her narrative was seen as too complicated for the jury: "I'd named so many names."

Nobody's Girl, published Tuesday by Knopf, gives the most detailed account yet of Giuffre's life, her abuse at the hands of Jeffrey Epstein, her allegations against Prince Andrew and her battle for justice through the U.S. civil courts.

But she also describes her response to not being called as a witness in the sex trafficking trial that saw Epstein's ex-girlfriend Ghislaine Maxwell jailed for her role in facilitating Epstein's campaign of abuse.

Giuffre died in Australia in April after what her family described as a suicide. Knopf said she had made it clear she wanted the book to be released.
