If you’ve followed the Expeditionary Force series this far, Ground State: Expeditionary Force, Book 19 is exactly the hit you’re waiting for. The mission starts as a win — the enemy Gateway is gone — but the celebration lasts about five seconds. Two new threats are now loose in the galaxy, armed with ships that make Valkyrie look outdated. A fair fight? Not even close.

This is where Craig Alanson does what he does best: pushing Joe and the Pirates into situations where brains matter more than firepower. Expect bad ideas, risky plans, sharp banter, and that familiar mix of tension and humor that keeps the series addictive. It never feels recycled. The stakes are real, and the consequences stick.

The audiobook shines thanks to R.C. Bray, who once again nails the timing, sarcasm, and emotional beats. His performance turns dialogue into something you feel, not just hear. At around 20 hours, the duration works in your favor — long enough to sink into the story, short enough that it never drags.

Written by Craig Alanson and produced by Podium Audio, this one’s easy to recommend. If you like smart sci-fi with laughs, tension, and momentum, hit play. You won’t want to stop.
