FROM THE WORLDWIDE #1 BESTSELLING AUTHOR BEHIND EMMY- AND GOLDEN GLOBE-WINNING HBO SERIES BIG LITTLE LIES AND SMASH-HIT NOVEL THE HUSBAND'S SECRET

One luxury retreat. Nine perfect strangers. Ten days. What could possibly go wrong?

Luxury health and wellness retreat Tranquilium House promises rest and relaxation - exactly what these nine strangers are looking for.

But the resort director has something else in mind. A very different, and very dark, agenda.

These nine strangers have no idea what's about the hit them . . .
