Earthfasts.
It starts with a noise reverberating in the hill. David and Keith see a boy appear from the ground, carrying a candle and beating a drum. He is an 18th-century drummer boy, who will have an irreversible effect on both their lives. Extraordinary things start to happen - standing stones move, giants stalk the hills, and wild boar rampage through the town. Then, David vanishes, and Keith must search through time for his friend...In the forty years since its first publication, "Earthfasts" has become an indispensable classic.
