For 15-year-old Daphne Ann Post, the summer of 1976 at Lake Carlson should be filled with new friendships and carefree late-night parties. But something darker lurks beneath the surface-her chilling premonition that someone is going to drown.

Wishing she could escape the shadow of her fractured family and her mother's too-soon rebound relationship, Daphne reluctantly heads to the family lake house in Northern Indiana. The tension with her mother is thick-especially when Daphne is the only one who knows her mom's boyfriend is hiding a dangerous secret. But Daphne's burden is far heavier than family drama. She harbors an unsettling gift-an ability to know the hidden truths of anyone she touches.

Last year that same intuition failed her when her best friend ignored Daphne's warning before a tragic accident. Now everyone at school blames Daphne for what happened. Haunted by guilt, Daphne is determined to keep her ability a secret.

When she meets the Vaughans-cool, popular, and effortlessly perfect next-door neighbors-Daphne is drawn into their world, seduced by the thrill of fitting in. Over the summer, whispers of danger from the lake grow louder. Her intuition screams someone will die, and not even the haze of weed can numb her fear.

The clock is ticking. Daphne knows that to save a life, she'll have to confront her darkest secret and risk losing everything she's worked so hard for. Can she stop the inevitable without exposing her truth? Or will the lake claim a victim-this time, someone she loves?
