When Tim Herring's family moves to the village of Lushbury near Stonehenge, strange things begin to happen. . . Who is the mysterious girl, Domino, and why is she hiding in Tim’s garden? Why do the birds of Lushbury only fly in straight lines and why do the church bells toll when the building has lain derelict for years? Tim's questions are soon answered as the children are pitched into a desperate race to protect an ancient secret buried beneath the Standing Stones –but can they really hope to win against such a terrifying enemy?
