Look, I have a bone to pick with John Scalzi. I finished Old Man's War thinking I had a nice standalone sci-fi romp to recommend to people. "Oh yeah, it's great, you can just listen to that one." And then I made the mistake of starting Ghost Brigades on a Monday morning commute and now I'm four books deep into this series and my Audible credits are crying.
This is basically a nature vs. nurture thought experiment wrapped in military sci-fi, and honestly? It works way better than it has any right to.
The Clone Identity Crisis That Actually Delivers
So here's the setup: the Colonial Defense Forces need to figure out why one of their top scientists defected to an alien alliance. Their solution? Clone him, shove his memories into the clone's brain, and hope something sticks. When it doesn't work immediately, they just... give the clone to their special forces unit and hope for the best. (Government efficiency at its finest, am I right?)
Jared Dirac - the clone - starts as basically a blank slate soldier. Perfect for the Ghost Brigades. No pesky human attachments, no moral qualms, just pure combat optimization. But Boutin's memories start leaking through, and suddenly you've got this genuinely fascinating identity crisis playing out between firefights.
I was not expecting to get this invested in a philosophical question about consciousness on the 6:47 AM train, but here we are. Scalzi does this thing where he sneaks in genuinely interesting ideas about what makes us us without ever getting preachy about it. The pacing helps - there's enough action to keep you engaged during the slower character development sections.
William Dufris: Not Ray Porter, But Solid
Okay, I'll be honest - I was initially skeptical because I'd gotten used to certain narrators for my military sci-fi fix. Dufris has a different vibe. More... earnest? His voice is clean and clear, which matters when you're half-awake and surrounded by other commuters who are definitely not interested in hearing about alien alliances through your headphone bleed.
He does good work differentiating the characters, especially the Ghost Brigade soldiers who could easily blur together. The tone matches the material - serious when it needs to be, but not so grim that you forget this is supposed to be fun. Some reviews mentioned he can get a bit dramatic at points, and yeah, I can see that. There were a few moments where I thought "okay buddy, dial it back like 10%" - but honestly, for military sci-fi, I'd rather have someone who commits than someone who phones it in.
The production quality is solid. No weird audio artifacts that pulled me out of the story, which is more than I can say for some audiobooks I've suffered through.
Where It Clicked (And Where It Dragged)
The middle section - where Jared is integrating into the Ghost Brigades and Boutin's memories are slowly surfacing - is genuinely compelling. There's this tension between who Jared is becoming versus who he was "supposed" to be, and Scalzi handles it with more nuance than I expected from a book with this much shooting.
The pacing isn't perfect, though. There are stretches where the political maneuvering between the alien races felt a bit... dense? Not bad, just slower. I found myself zoning out during some of the strategic briefing scenes - though that might have been the 6 AM factor more than the book's fault.
The payoff in the final third is worth it. I finished the last two hours during a particularly brutal on-call night (thanks, distributed systems) and I was fully locked in despite running on caffeine and spite.
The ROI Calculation
At 10 hours 20 minutes, this is basically a week of commutes for me. Is it worth it? Yeah, pretty much. It's not quite as immediately grabby as Old Man's War - the first book drops you right into the action, while this one takes more time to build. But the character work is stronger, and the questions it raises about identity and choice stuck with me longer than I expected.
Listen if: you want sci-fi that's smart but not homework - perfect for long commutes, gym sessions, or background for tedious debugging sessions.
If you're looking for something in a similar vein but with even more survival-against-impossible-odds energy, Space Prison delivers that in spades.
Skip if: you haven't read Old Man's War first. You could technically start here, but you'd be missing context that makes the world-building land better.
I'm already three chapters into the next book in the series. My boyfriend Kevin asked if I was ever going to listen to anything else and I told him this was his fault for introducing me to Scalzi-adjacent military sci-fi in the first place. He did not find this argument compelling.
