Nursery fun and games
The Fourth Bear - Jasper fforde
OK, it's kind of throwaway and a bit lightweight but on the other hand the two series of Fforde books really are pretty entertaining. The 'Thursday Next' books, which allow Fforde a braoder range of literary allusions, work better I think than the Nursery Crime series of which this is the latest instalment.
Still, it is a welcome addition to the list but if you've not read any of his stuff this would not be the best place to start.
(Note: Stars for entertainment value rather than pure literary merit.)
