“Sarah Hall's writing has conquered the body and the soul and now it conquers the wind itself. She gets better with every word she writes.”–Daisy Johnson, author of Sisters and The HotelFrom the twice-Booker-nominated writer of Burntcoat, a bold and astonishing literary masterpiece that explores faith, connection, and our relationship to the natural world.Helm is a ferocious, mischievous wind — a subject of folklore and awe, part-elemental god, part-aerial demon blasting through the sublime landscape of Northern England since the dawn of time.Through the stories of those who’ve obsessed over Helm, an extraordinary history is formed: the Neolithic tribe who tried to placate Helm, the Dark Age wizard priest who wanted to banish Helm, the Victorian steam engineer who attempted to capture Helm — and the farmer’s daughter who fiercely loved Helm. But now Dr. Selima Sutar, surrounded by infinite clouds and measuring instruments in her observation hut, fears human pollution is killing Helm.Rich, wild, and vital, Helm is the story of a singular life force, and of the relationship between nature and people, neither of whom can weather life without the other.
