His novel One Day (recently adapted for Netflix) was an international publishing phenomenon and the iconic love story for a generation, while Us placed him on the Man Booker Prize long list. His latest novel, You Are Here, is a love story which unfolds on a walk across the north of England. It’s the story of two lonely people, both a little lost and wary of new company. But, over many miles, as they start to talk and share stories, the possibility of a new beginning opens up before them. Witty and thoughtful as ever, David Nicholls talks to BBC broadcaster Samira Ahmed about first encounters, second chances and finding the way home.
