Murdoch, Emily

Enduring a difficult existence in the woods with her younger sister and the mentally ill mother who abducted them, Carey is found by her father and thrust into a new world that is overshadowed by a secret about her sister's silence.

Living in a broken-down camper hidden in a forest, fifteen year-old Carey and her younger sister, Jenessa, just have each other. After their mentally ill mother disappears for good and they are put into foster care, Carey must face the truth of why her mother abducted her ten years ago, and find the reason why Jenessa has not spoken in over a year.
