Rules for the girls' trip:

1) No kids

2) Out-of-office on

3) Keep the drinks flowing

4) DON'T TELL ANYONE WHAT WE'VE DONE

When Charlotte and Bianka meet, they quickly become inseparable. Wanting to bring fresh energy into her life, Charlotte invites Bianka on her annual girl's trip to Ibiza with her childhood friends.

They arrive wanting to break the routine, to escape the monotony of everyday life. To drink too much, to flirt with strangers, to live life dangerously.

To take things too far.

No one could have planned for just how far these women were willing to go... Or how spectacularly this trip will ricochet through their lives back home.

They say that what happens in Ibiza, stays in Ibiza - if only that were the case...

A dark, addictive psychological thriller that will keep you guessing until the very end, for fans of Harriet Tyce, B.A. Paris and Liane Moriarty.
