The Last Time I Lied By Riley Sager

Fifteen years ago, summer camper Emma Davis watched sleepily as her three cabin mates snuck out of their cabin in the dead of night. The last she–and anyone–saw of them was Vivian closing the cabin door behind her, hushing Emma with a finger pressed to her lips.

Now a rising star in the NYC art scene, Emma turns her past into paintings.. They catch the attention of Francesca Harris-White, the socialite and wealthy owner of the very same Camp Nightingale–and when Francesca implores Emma to return to the camp as a painting counselor, Emma sees an opportunity to find closure and move on.

Yet, it is immediately clear that all is not right at Camp Nightingale. Already haunted by surfacing memories, Emma is suddenly plagued by a security camera pointed directly at her cabin, mounting mistrust from Francesca, and, most disturbing of all, cryptic clues Vivian apparently left behind about the camp’s twisted origins. And as history begins to repeat itself and three girls go missing again, Emma must face threats from both man and nature in order to uncover all the buried secrets–including what really happened all those years ago.
