Diary of a Nobody - the gentle but exquisitely chronicled suburban adventures of a frequently exasperated man living below his true station.
Christie Malry's Own Double Entry - a lowly clerk introduced to double-entry book-keeping decides to keep his own real life tally. Very dark but incredibly funny.
The Collector's Collector - the ever-eventful life of a pot, narrated by the pot itself. This makes it sound like some kind of junior school writing project but it is witty, acerbic and a rollicking good read.
