Zoe's younger sister Holly has been trapped in a mental hospital for a year and a half, and since the beginning of Holly's stay, Zoe has been miserable. But a new patient in the form of seventeen year old Finn may make things brighter for Zoe than even the blinding walls that line every corridor of the hospital except the kids ward. But as Zoe moves on in her life, will she let herself forget about her sister's? A story that mixes teenage and sisterly love, and sadness and joy, and hopefully has a happy ending.
