Not much of a review because I'm not entirely sure what the plot was about in this one.
Thursday goes into the book world to stay out of danger during her pregnancy and ends up in a number of adventures with lots of book characters as part of the Jurisfiction squad.
I finished it and liked it better than book #2.
The ending where Fforde takes as swing at Amazon and DRM and self-publishing without quality control made me laugh a number of times.
And of course, Pickwick was excellent in this
We also get to read about the egg hatching.
