In all honesty, I'm writing this review a couple of weeks after I finished the book, so I can't really go into any details. In retrospect, it feels like it's less about the wild cards and more of a gangwar thriller with some superpowers thrown in. There were lots of characters, perhaps more than we've seen in the other books, but nobody really gets an indepth treatment of their inner life. I felt that was disappointing, I was hoping Jack and Bagabond would have a chance to tell more of their story.
In a series this long, there always has to be some volumes that are a bit weaker than the rest, but that doesn't necessarily take away from the series. This book is an example of that phenomena.
