Wildcard was a wild fucking ending. I loved it! The way everything wrapped up was amazing. Marie Lu did that shit. I appreciated the moral tension within Emika as she made her choices and decisions. The audiobook was very well done. There is a difference between this book and Warcross. I think there is less tech and gameplay in this book that might throw some people off. It's definitely more focused on Hideo and Zero and taking either one of them down.
