Didn't think I'd like this book when I started reading it, but it got really, really good at about the halfway point once the Grey King storyline was introduced. Took me a bit of time to get used to how all of the chapters were chronologically out of order. The book is kind of like "Oceans Eleven" set in a Renaissance Italy-esque city (except the city is built on top of the ruins of an extinct alien city, though this is mostly unimportant to the story).
