The Girl in the Coppertone Ad

Seventeen-year old Trey Munney's world was shaken when she lost her father in a tragic accident. One year later, she hopes the annual vacation to her uncle's beach house in Maine will help soothe her emotional pain. But the trip is a string of disappointments. Most of her extended family can't make it. Her summer crush is cold to her. Her widowed mother spends a little too much time with the single guy next door. Even her iPhone dies. Then she meets local girl Ricki. Trey and Ricki complete one another. They say what the other is thinking. They share a unique sense of humor. They could sit silently for hours, happy just to be together. It's perfect. Except for one little problem: there's increasing evidence that Ricki may not actually exist. Is Trey slowly losing her mind? Or is something supernatural walking the shores of Maine?
