I'd heard really good things about this book and I find myself wondering how much of the book actually needed to be set at Longbourn to work. I mean, elements of the narrative intersected with P&P, but the story itself could just as easily have happened absent Austen's world.
So there's the part of the story that's something of an ideological stance...not against Austen per se, but not aligned with her either, where much of the non-description of characters and places and the functioning of the world is replaced with actual depictions of work (which, of course, Austen would have been more than familiar with).
And then there's the rest of the narrative, which is a nice narrative about the lives of the servant classes and some thoughts about the people who are not often written about.
I'm just not sure whether they connect.

Also, I will admit that some of the characterizations just felt...off. The language, on the other hand, worked very well for me because Baker at no point attempted to BE Jane Austen and wrote the characters in her own voice. And that was infinitely better than attempting Austen.
