Features three interlinking stories about Edinburgh. This book presents three writers' radically different takes on Edinburgh life - a social mix that ranges from Welsh's Leith junkies to McCall Smith's New Town haute bourgeoisie.
All proceeds from the book will go to the One City charity, which fights social exclusion in the city. Edinburgh's Lord Provost Lesley Hinds said: 'This book project is exactly what One City is all about. The idea of three successful Edinburgh authors, with very different perspectives, getting together to raise awareness and money by using their talent and creativity, is really exciting.'
