The Anthologist by Nicholson Baker

Paul Chowder is suffering from writer's block and his long-time girlfriend has left him. As Paul wanders through the days trying to write the introduction to a long overdue poetry anthology, he struggles to rediscover his own poetry as well. Love him or hate him, Paul's stream of consciousness narration never fails to entertain.

This is a book that grew on me as I read it. You kind of want to bop Paul on the head but there is also a fascination about how (or if) he will manage to pull himself out of the mess he has made of his life.
