'Follow your heart and speak your truth.'For Samantha Miller's young fans - her 'girls' - she's everything they want to be. She's an oracle, telling them how to live their lives, how to be happy, how to find and honour their 'truth'.And her career is booming: she's just hit three million followers, her new book Chaste has gone straight to the top of the bestseller lists and she's appearing at sell-out events.Determined to speak her truth and bare all to her adoring fans, she's written an essay about her sexual awakening as a teenager, with her female best friend, Lisa. She's never told a soul but now she's telling the world. The essay goes viral.But then - years since they last spoke - Lisa gets in touch to say that she doesn't remember it that way at all. Her memory of that night is far darker. It's Sam's word against Lisa's - so who gets to tell the story? Whose 'truth' is really a lie?'You put yourself on that pedestal, Samantha. You only have yourself to blame.'
