I've had a complex relationship with The Expanse series, disliking its TV series and yet giving it a second chance via the novels. Abaddon's Gate has a lot of what I like about the series: the action is excellent, and it has a decent mystery (though not a police procedural) that adds a thrill to the times when the guns aren't firing. Holden is the glue that keeps the series anchored, and while he's an enjoyable presence, I'm also happy that his flaws are called out in-universe.

And yet... none of these books have been stand-out hits for me.

Abaddon's Gate is just serious enough to give the universe a sense of gravitas. But it never fully commits to either being serious business or a fun, easy read for the evening. The series is filled with high stakes (the fate of human civilization) and plenty of treacherous moments. I get a sense of loss, and the scope of what's going on doesn't allow me to turn off my brain, but the moment the going gets tough, we hit a patch of comic relief. Nowhere is this more obvious than the recurring joke about how Amos is a cold-blooded murderer but at least he's on our side.

Humor is fine, but the series is already short of dramatic tension. It's been a long time since Shed's demise, and nothing since then has made me worry for our heroes in the slightest. The antagonists in this series rarely appear on-screen, and if they do appear, are impotent. A constant stream of new POV characters allows us to stay emotionally uninvolved. When all these elements come together, I'm left with a novel that was entertaining, but forgettable.

Recommended with reservations.
