Well, that was a mess. Okay, first the good. You will never get bored with a lack of action. This book constantly has something going on and it moves at a very fast pace. The story is basically the fall of pseudo-Roman empire, with a Nero type as Emperor.
Second, the bad. There are so many characters, none of which are fleshed out and so you don't have anyone to grow attached to, except maybe Tacitus. I'd say there are 20 or more names to try to keep track of, most with very little personality. It was a nice try, but the author needs to pick some main characters and focus on them. It seems like she wants to make the story about the Empire itself and those never work.
