In Pullhair, there was a church, a school and a fire station. The school and the fire station were rarely used. In Pullhair, also, was a stone farmhouse, known by the four women who lived there as CALA, haven.

Cala blends the occult with the modern, following a small community of women living on the outskirts of their Hebridean society, where they have always followed the rigid rules set down by one of their ancestors, a suspected witch. 

Cala, a stone farmhouse on the edge of a village in the Outer Hebrides, is home to four women – witches the locals say – who scratch out a living on its land. But after ten years of relative harmony, fractures are beginning to appear among them. Sick of scavenged seaweed and thin soup, eighteen-year-old Euna decides to go in search of a different way of living.
