Query: Dissolution ... well written and dark

Very well written. The story kept my interest and I was particularly intrigued by the view of how the society of that time worked (according to the author who has some expertise on the subject).The characters run the range of noble, flawed, base, intriguing -- sometimes all in the same body.Though easy reading this is not a 'light' or feel good book.
