Wren Ashwood, an unassuming sixteen-year-old, finds herself living with her aunt and uncle a year after losing her mother in a fatal car accident. Upon her arrival, she stumbles across a shortcut through the woods that leads to her school. There, she meets Aaron, a charismatic boy with brilliant green eyes who takes particular interest in her.
Just when Wren begins making friends and settling into her new life, things take a turn. She feels herself irresistibly drawn into the forest, despite her aunt's warnings. Quiet footsteps trail behind her on the mossy forest floor, their bearer ever elusive. About one thing Wren is certain: the forest is calling.
