About This Audiobook

The mission to destroy the enemy Gateway was literally a smashing success.

Except the Pirates were too late, and now not one but two of the enemy are loose in the galaxy. And they are equipped with starships more powerful than Valkyrie. A direct fight would be hopeless, so the Pirates must rely on wacky ideas from the mushy brain of a monkey—and some serious sketchiness.

The Expeditionary Force saga continues in book 19 from epic sci-fi writer Craig Alanson and narrated by none other than R.C. Bray.

Quick Take

  • Narration: R.C. Bray is the defining voice of the Expeditionary Force universe, and nineteen books in he remains as sharp and comedically precise as ever.
  • Themes: Military sci-fi comedy, impossible odds, human ingenuity against superior forces
  • Mood: Propulsive and funny with escalating stakes
  • Verdict: Book 19 delivers exactly what long-term ExForce listeners want, though minor audio pacing issues noted by some reviewers do not significantly disrupt the experience.

There is something genuinely impressive about a series maintaining its comedic voice and creative momentum nineteen books in. I finished Ground State over two evenings, having been in the Expeditionary Force universe since the early installments, and Craig Alanson continues to do what almost no long-running military sci-fi series manages: he makes the humor feel earned rather than habitual, and he keeps raising the narrative stakes rather than coasting on established dynamics.

Book 19 arrives in a specific place in the saga. The mission to destroy the enemy Gateway technically succeeded, but the Pirates arrived too late, and now two enemy forces equipped with ships more powerful than Valkyrie are loose in the galaxy. Alanson’s setup for this installment forces exactly the kind of lateral thinking that has always defined the series: when direct confrontation is hopeless, what wacky idea does a monkey’s mushy brain produce? That question has powered 18 previous books, and the answer here is characteristically inventive and genuinely surprising given how long the series has been at this particular game.

The Penultimate Book Problem and How Alanson Handles It

Book 19 carries the structural burden of being the penultimate entry in the Expeditionary Force saga. Penultimate installments in long series face a specific challenge: they need to escalate meaningfully while positioning the finale without feeling like pure setup. Ground State threads this better than most. The stakes are genuinely elevated beyond what the series has presented before, not simply restated at a louder volume. Reviewers who describe this as a book that kicked the story and stakes up a notch are identifying something real rather than simply expressing enthusiasm for a beloved series.

What Alanson does particularly well here is balance the series-long emotional investment with enough standalone narrative satisfaction that the book does not feel like a bridge. The humor remains functional rather than decorative, and the friendship dynamics that have anchored the series since book one continue to carry emotional weight. This is not a series that has run out of things to say about its characters; it is a series that is actively choosing how to conclude, which is a meaningfully different thing.

The RC Bray Factor: Can a Narrator Define a Series

The answer, in this case, is definitively yes. R.C. Bray’s performance as the voice of the Expeditionary Force universe is not simply competent narration supporting good writing. It is a creative collaboration that makes the humor land differently than it would in print. His comedic timing, his handling of the ongoing banter, and his ability to voice an alien artificial intelligence with both menace and absurdist wit have become fundamental to how this series works. Reading these books in print after hearing Bray is a noticeably diminished experience.

One reviewer notes that Bray does his usual incredible job narrating even while flagging some odd spacing issues in the dialogue early in Ground State, where he reads a sentence, pauses for one to one and a half seconds, then continues. These pauses appear to be audio editing artifacts rather than intentional choices, and they are concentrated in the opening chapters. They are worth knowing about, but listeners who have been with the series long enough will find their investment carries them through without serious disruption. By mid-book, the issue fades as a concern entirely.

Where Ground State Fits in the Arc and Where to Start the Series

Ground State is emphatically not an entry point. The series has nineteen books for a reason, and Alanson builds his emotional and narrative payoffs on accumulated context going back to book one. Jumping in here would be like joining a long-running television drama in its final season: technically possible, immediately confusing, and fundamentally unsatisfying as an experience.

For readers who are already in the Expeditionary Force universe, this installment rewards the investment. The series maintains a consistency of voice that few military sci-fi franchises at this length achieve. A long-term listener who described the series as deserving Hugo Awards it has not yet received is expressing genuine enthusiasm for something that operates at a level above most self-published space opera, and that assessment holds for this particular entry. A reviewer who attended book 19 fresh describes the book as still funny 19 books in, which is the highest and most specific compliment the series could receive.

The correct listening approach is to start from book one, Columbus Day, and build toward Ground State. The series is long, but Bray’s narration makes even the 15-to-20-hour installments feel shorter than they are. By the time you reach book 19, you will understand exactly why readers describe themselves as devastated that the series is nearly over.

What This Edition Gets Right and What Its Editing Gets Wrong

The audio editing issue documented by multiple reviewers deserves a clear-eyed assessment before you spend nearly 20 hours here. The odd spacing in dialogue appears primarily in the first third of the book and is consistent enough that it is clearly a production-side problem rather than a narration choice. Bray himself sounds as sharp as ever; the issue is with how the final audio was assembled around his performance.

Podium Audio produces strong work generally, and this kind of artifact in an otherwise well-produced long-running series is frustrating precisely because the series has set a high standard. It does not ruin Ground State, but it is genuinely present and it would be dishonest to dismiss it entirely. Consider it the audiobook equivalent of a small number of typos in an otherwise excellent novel: annoying, not disqualifying, and worth knowing about before you start.

Frequently Asked Questions

Can I start the Expeditionary Force series with Ground State, book 19?

No. The series relies heavily on accumulated character relationships and plot history. Start with Columbus Day (book 1) to get the full experience. The good news is R.C. Bray’s narration makes every installment engaging.

Some reviewers mentioned audio editing issues with pauses in dialogue. How significant are they?

The pacing artifacts are real but concentrated in the early chapters. Multiple reviewers noted them, describing one-to-one-and-a-half-second pauses mid-dialogue. They do not significantly affect the second half of the book.

Is Ground State truly the second-to-last book in the Expeditionary Force series?

Yes. Alanson has confirmed the series is concluding, and Ground State is described by reviewers as the penultimate installment. The finale had not yet been released as of this review.

Does the humor still work 19 books in, or does it feel repetitive by this point?

Multiple reviewers specifically note the humor remains effective at this stage, which is a genuine accomplishment. Alanson keeps finding new situations for the established comedic dynamics rather than retreading old ground.

A Great SF Series. Read Them All!

You know what is wrong with this series? Nothing. Except it has not been given Hugo Awards yet! There are multitudes of space operas self published on Amazon.
