Idol: The must read, addictive and compulsive book club thriller of the summer

'IDOL is fresh, glamorous, and surprising, taking an issue we all care about and with a deft twist, recalibrating our position. It dazzles us before revealing the darkness at its heart. Louise O'Neill is not afraid to take on a taboo but somehow always makes it utterly compelling. This is such an exciting book.' Marian Keyes

'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.'
