In second-century Britain, Macey and a gang of fellow deserters from the Roman army hunt and are hunted by deadly local tribes. Fifteen centuries later, during the English Civil War, Thomas Rowley hides from the ruthless troops who have encircled his village. And in contemporary Britain, Tom, a precocious, love-struck, mentally unstable teenager, struggles to cope with the imminent departure for London of his girlfriend, Jan.
Three separate stories, three utterly different lives, distant in time and yet strangely linked to a single place, the mysterious, looming outcrop known as Mow Cop, and a single object, the blunt head of a stone axe.
