Things have been building up for two books and now it is time to find out how it all plays out. Cassius' plan to destroy the religous zealots of the New Earth Tribunal is simple in concept - you can't worship the spirit of the Earth if there is no Earth, so he plans to do just that. It is also just as likely that his plans involve more than just revenge. Most of the rest of the characters are pawns in his game, but they have started to figure that out, and the word is spreading that the war was orchestrated by Cassius from the start. This fact is prompting others like Sage and Talon to pursue their own agendas, so the final confrontation of this war is going to be a wild ride.

Book one of The Circuit series, Executor Rising, did a good job of setting the stage for the rest of the story. The main characters are all established, their backgrounds and motivations are mostly clear, and the state of the solar system is such that the impending conflict will have dire consequences depending on how it all turns out. However, none of the factions can be classified as the good guys in this story so I do not find myself emotionally invested in any particular outcome, or character. Normally that is an issue for me, but in this case I found myself eager to know how it turns out anyway.
I remember when I first started reading The Expanse series and how I was surprised that I found it compelling even though human space travel was limited to our own solar system. No warp drives or hyperspace conduits seemed pretty boring at first, but I eventually came around because limiting the scope of the story to our own solar system made it that much more real. Although similarly limited to our solar system, Executor Rising puts aside realism and instead offers up something much farther out there in concept. The Earth is no longer a habitable planet and mankind instead has The Circuit, which is an interdependent ecosystem that uses Solar Arks to transport needed materials between human colonies that are spread across the solar system.
