This was a fascinating stream-of-consciousness type of story, all taking place in the mind of a single person. Some of their thoughts are mundane, some philosophical, sometimes they think up stories about people around them. This book is pretty slow-going since almost nothing really happens, but if you're in the mood for something contemplative and thought-provoking, then it's definitely worth reading.
PS. If you're not in the US, buy this from smashwords - amazon adds something extra to the price for shady reasons (i.e more than VAT).
