Annie and Duncan are a mid-thirties couple who have reached a fork in the road, realising their shared interest in the reclusive musician Tucker Crowe (in Duncan's case, an obsession rather than an interest) is not enough to hold them together any more. When Annie hates Tucker's 'new release', a terrible demo of his most famous album, it's the last straw - Duncan cheats on her and she promptly throws him out. Via an internet discussion forum, Annie's harsh opinion reaches Tucker himself, who couldn't agree more. He and Annie start an unlikely correspondence which teaches them both something about moving on from years of wasted time.

Nick Hornby's compelling new novel, four years after A Long Way Down, is about the nature of creativity and obsession, and how two lonely people can gradually find each other.
