Shortly after her 16th birthday, Sunshine Griffith and her mother, Kat, move from sunny Austin, Texas, to the rain-drenched town of Ridgemont, Washington. Though Sunshine is adopted, she and her mother have always been close, sharing a special bond filled with laughter and inside jokes. But from the moment they arrive, Sunshine feels her world darken with an eeriness she cannot place.
In the days that follow, things only get stranger. Sunshine is followed around the house by an icy breeze, phantom wind slams her bedroom door shut, and eventually, the laughter Sunshine hears on her first night evolves into sobs. She can hardly believe it, but as the spirits haunting her house become more frightening, and as it becomes clear that Kat is in danger, Sunshine must accept what she is, pass the test before her, and save her mother.
