The discovery of an ancient, bog-preserved body in Scotland triggers a supernatural connection between a modern teenager and a girl from the Iron Age. Lea Green finds herself inextricably bound to Ana, a Celtic chieftain's daughter, through a shared, ostracizing psychic ability and the presence of identical stone circles. As Lea grapples with her own isolation in contemporary Australia, she must navigate the echoes of Ana's life across two millennia. The narrative shifts between these two distinct timelines, utilizing the mystery of the bog body to bridge the gap between the ancient past and the present day.

The premise suggests a narrative that prioritizes atmospheric tension and the psychological parallels between two isolated protagonists. By linking the ancient Celtic world with modern Australian life, the story emphasizes the timeless nature of feeling like an outsider. The inclusion of supernatural elements serves to heighten the stakes of the girls' personal struggles rather than focusing solely on the historical mystery. Readers likely find the connection between the two stone circles to be the central anchor for the book's thematic exploration of identity and heritage.
