Impossible Causes

Four elements. Four seasons. Four points on the compass. Four teenage girls. And one body.

In Mayhew’s mesmerising thriller, a remote and deeply religious island with a history of paganism is riven when a man’s body is found in a stone circle. As rumours spread and tensions rise, and fog descends, sealing the island off from the mainland, the four teenage girls of Lark Island find themselves accused of witchcraft – and murder.
