Where Wild Cards introduced the setting and spanned decades dealing with the introduction of the wild card virus and how the world diverged from our own, Aces High feels a lot more focused, dealing primarily with two plot lines: the arrival of an alien ‘swarm mother’ (a hive mind/bio ship intent on eating planets, as one does) and the Masonic conspiracy we first got a glimpse of in Fortunato’s introduction.
The story starts out a bit rough. I don’t really care for the Mason/Fortunato’s plotline. But the swarm stuff is pretty cool and there are a number of fun new characters along with expanded worldbuilding. I like the additional focus. It makes me wonder/expect if each book will have a single topic or two to focus around.
