Let me start by saying, if you’re 6 books into an ongoing series like this, than I’m going to assume you’re in it for the long haul, and I think you’ll enjoy the hell out of this one too.

James S.A. Corey (Ty Franck and Daniel Abraham) refer to their Expanse series as 3 duologies and a trilogy (forthcoming books 7,8 & 9) to cap it all off. Leviathan Wakes/Caliban’s War tell a fairly contained story about the protomolecule in the style of noir and political thriller respectively. Abaddon’s Gate/Cibola Burn deal with the expansion out into deeper space as a ghost story/western, but Nemesis Games/Babylon’s Ashes really read like two halves of the same larger novel. They are much more deeply intertwined than any of the other sets in the series. If each novel is a different genre married into the science fiction backdrop, then I’d call Nemesis Games a survival tale, and Babylon’s Ashes a great russian tragedy a la Dostoyevsky or Tolstoy.

Gone is the simple narrative structure of the first five books, each — excluding Leviathan Wakes — with four alternating POV characters. Instead we’ve got nineteen unique points of view. But if you’ve made it this far, you’re ready for that kind of complexity, you’re already intimately familiar with most of these characters. Holden, Pa, and Filip are the main ones, but we get lots of tertiary views on the action and plot. I really love this change to the structure, and can’t help but think that The Expanse television series influenced it in some way. It does feel more like the way that a TV show handles narrative. We get a perspective from nearly every main and secondary character still living, and some new ones as well. This opens up the world even more, something that this series has done so well along the way.

The main story involves the aftermath of the events of Nemesis Games, and how those events affect everyone, both inside and outside of the Sol system from here on. The Free Navy is causing havoc all over the place and has essentially taken over several large belter settlements. Holden and crew are caught in the middle, working with Avasarala and Fred, trying to do what they can to clean things up and bring Marcos down. Meanwhile, a splintered remnant of the MCRN is working in the shadows, silently preparing for what’s to come. And don’t forget the even larger threat looming on the periphery: whatever killed the protomolecule makers.

It’s a sad story, ultimately a tragedy, but there are several threads woven throughout that are paving a path to redemption for some, and death and destruction or others. It all makes for a terrific story, and moves at a breakneck pace toward a very tight conclusion. One that comes together so smoothly in fact, that a lot of people have been confused, thinking this was the end of the entire series. Of course, that isn’t the case, but I think you could approach this as the penultimate end to some of the earlier narratives begun all the way back in the first novel. Call it a semicolon; the conclusion of the series to follow.
