Never try to open the locked doors. Never question what you are told. And never attempt to cross the Boundary. Kept inside an eerie Victorian-era estate for their entire lives, Penny and her five friends have had no contact with the outside world, with their only windows being a handful of books, sinister master and a secretive housekeeper. Fed up of living a mystery, Penny begins breaking all the rules and finally tries to escape; but what she uncovers is far more devastating than she could have imagined. It rapidly becomes a deadly struggle for the truth in a world where nothing is what it seems, and friendship can be either your greatest weapon or biggest liability.
