From the widely renowned author Andrew O'Hagan, a heartbreaking novel of an extraordinary lifelong friendship. Everyone has a Tully Dawson: the friend who defines your life. In the summer of 1986, in a small Scottish town, James and Tully ignite a brilliant friendship based on music, films and the rebel spirit. With school over and the locked world of their fathers before them, they rush towards the climax of their youth: a magical weekend in Manchester, the epicentre of everything that inspires them in working-class Britain. There, against the greatest soundtrack ever recorded, a vow is made: to go at life differently. Thirty years on, half a life away, the phone rings. Tully has news. MAYFLIES is a memorial to youth's euphorias and to everyday tragedy. A tender goodbye to an old union, it discovers the joy and the costs of love.
