I found myself doubting and be disappointed with the first half of this book. Indeed, while the story was indeed interesting, I felt something was missing. 
 And yet I guess the end kind of won me over in a strange way. I couldn't not really say why (I guess it is a little bit of satisfaction after a book full of horrors) but it did (even if it felt a little bit flat) and that's why I'm happy to give 3 stars A Madness so Discreet when I first thought about giving a 2 stars rating, tops. 
 Yet, since I did not enjoy a big part of the book, I'd recommend you to check out this book at the library if you want to read it, as I would not put it in the "must buy" category.
