In short, I feel like the plot was a lot more focused than in the last book and now that I've gut to know the characters they were a lot more fun to read about. I liked the jazz aesthetic in this one. 
 My only issue was that it did the thing where it mentions a name, then forgets about it for 200 pages and by then I've forgotten who that was. 
 Better than the first book, and hopefully the next one will be better again.
