There is the Cornwall Lamorna Ash knew as a child - the idyllic, folklore-rich place where she spent her summer holidays. Then there is the Cornwall she discovers when, feeling increasingly dislocated in London, she moves to Newlyn, a fishing town near Land's End. This Cornwall is messier and harder; it doesn't seem like a place that would welcome strangers.

Lamorna Ash was raised with about as much Christianity as most people in Britain these days: a basic knowledge of hymns and prayers received via a Church of England primary school education; occasional brushes with religious services. But once she started writing about her two friends' unexpected conversions, she began encountering a recurring phenomenon: in an age of disconnection and apathy, a new generation was discovering religion for itself.
