From the #1 international bestselling author of I'm Watching You, whose thrillers have sold 2,000,000 copies worldwide. Three girls and their darkest secret... They vowed to hide the horrifying truth until their graves. It happened while they were studying at monastery school. Thirty years ago. To this day, Beth and Sally are still trying to overcome the trauma of what they did. Carol moved away from her former friends. There's nothing you can do about it - life. The main thing is that they all know for sure: their word is inviolable, no one will know anything. Ironically, it is the quiet, serene monastery that will forever hide their grave sin in the darkness of the past. They were mistaken. Shocking news: the monastery is closing, it will go under the hammer! This means that their terrible secret will inevitably be revealed, destroying the lives built with such difficulty. The time has come to fulfill the promise made to each other by three girls who valued friendship more than anything in the world.
