1am. An Iron Age hillfort in North Dorset. Away from dysfunctional families and small-town gossip, Viv and Daisy can be entirely themselves. With so much beyond their control, Fort is their stomping ground. Their escape. Until the ghost turns up. Best friends for as long as they can remember, their bond has survived school bullies, witchcraft, jealousy and vengeful cows. But at the end of a summer when everything is changing, can it survive the ghost?
