This book posed major problems for me. I got to the end of chapter 3 and still had no clue what the book was about. The information was there, yes, and I didn't care because the characters weren't believable, seemed shallow, there was no conflict, no tension, way too much narration and exposition, ... I caught myself several times skimming to find dialogue or something equally interesting.
There was a Downton Abbey/Upstairs, Downstairs vibe but it didn't come off at all for me, which is a pity as I love period pieces and am an avid Anglophile (okay, primarily an Albaphile).
This book may be some readers cup of tea and good for them, and it wasn't mine. The authorial voice, craft, and technique got in the way of the story.
