I really enjoyed this book. I'm not sure why, because it was utterly ludicrous in places. I was a bit surprised at how completely it wrapped up all the major plot and character threads; knowing it was the first book in a series meant I expected at least a couple of the subplots to linger. There were weirdnesses with the narration style (first person with some random omniscient jumping around) that I half expected to be explained via some kind of setting technology but never were. 
 Thursday herself was a decent character, but not why I read the book. When I pick up the sequels (and I will) it will be to see more of the setting, along with Jasper Fforde's amazing and energetic storytelling style.
