Well... This was a massive disappointment.
 
Pretty much the only good thing I have to say about it is that I enjoyed the way one of the expositions wasn't delivered via monologue - it was split between the pages,

Lenora telling the story

, and Kit's narration. Though this was at times slightly confusing to listen to on audio, I'm sure it would have been clear in print, and it was a nice way to get the info across without a lazy monologue. 
 
However, like everything else in this book, I was then disappointed when surprise, surprise there was an exposition monologue, and what a shitty one at that.

Like seriously?? She could walk and talk the whole time?? Not one SINGLE person, not even her 1-to-1 nurses who had looked after her for 40+ years noticed??? That was one ridiculous plot twist too many. Bloody hell.

 
 
I also guessed some of the major twists (

Including the obvious of Lenora not being Lenora, and Kit being related to the family in some way

), and the reveals towards the end felt so messy. Things didn't link up and it was bewildering (in a bad way).
 
Also, Paris yet again being romanticised by Americans. It's not that great folks!
