Natasha Carthew grew up in rural poverty in Cornwall, battling limited opportunities, precarious resources, escalating property prices, isolation and a community marked by the ravages of inequality. Her world existed alongside the postcard picture Cornwall, where wealth and privilege converged on sandy beaches and expensive second homes. In the rockpools and hedgerows of the natural world, Natasha found solace in the beauty of the landscape, and in the mobile library she found her means of escape. In this book she returns to the cliff-paths of her childhood, determined to make sense of an upbringing shaped by political neglect and a life defined by the beauty of nature. 'Undercurrent' is part-memoir, part-investigation, part love-letter to Cornwall.
