In this riveting tale that 'will keep you on your toes until the very end' (HelloGiggles), two couples embark on a toxic relationship after a night of sexual shenanigans, unaware of the manipulative teenager with an explosive secret at the centre of it all. From the bestselling author of The Party.

Low Morrison is not your average teen. You could blame her hippie parents or her dreary, isolated island hometown. Whatever the reason, Low just doesn’t fit in – and neither does newcomer Freya, an ethereal beauty and once-famous social media influencer.

After signing up for Freya’s pottery class, Low quickly falls under her spell. Buoyed by Low’s adoration, Freya is compelled to share her darkest secrets and deepest desires. Finally, Low feels a sense of belonging ... until Jamie walks through the studio door. Freya, Jamie and their husbands become fast friends, leaving Low alone once again.

Then one night, after a boozy dinner party, Freya suggests swapping partners. It should have been a harmless fling between consenting adults, but instead, it upends their lives.

And provides Low with the perfect opportunity to unleash her growing resentment.
