Sixteen year old Cass Sawyer wakes up in the woods with a head injury. She has no recollection of what happened. But she recognises where she is. The Haven. The idyllic, off-grid retreat her parents claimed would heal their broken family. As Cass searches the now deserted buildings, memories begin to trickle through. Her father’s erratic behaviour. Her mother’s pleas that they go back to town. The Haven’s charismatic, free-spirited leader. The strange girls that hang on his every word. And a nagging feeling- that Cass has done something terribly wrong. What happened at The Haven? Where is Cass’s family? And will they ever escape?
