This is Helm's life story, formed from the chronicles of those the wind enchanted: the Neolithic tribe who tried to placate it, the Dark Age wizard priest who wanted to banish it, the Victorian steam engineer who attempted to capture it - and the farmer's daughter who fell in love. But now Dr Selima Sutar, surrounded by measuring instruments, alone in her observation hut, fears the end is nigh. Vital and audacious, Helm is the elemental tale of a unique life force - and of a relationship: between nature and people, neither of whom can weather life without the other.
