I never really intended to read this book. In fact, I didn’t even know it existed until Andrew handed it to me in a parking lot, with all the subtlety of a kid’s first drug deal. All I needed was the book’s cover and tag line “the moon’s first murder is just the beginning.” And honestly, if I did not write for this site, I probably would never have picked it up. Luckily for me, I got more out of it than I expected. For a shallow premise, there is a decent amount of potential hidden in this mixed bag of goodies. With Gunpowder Moon, David Pedreira weaves physics and danger into an entertaining read despite its lackluster story, serviceable characters, and uninspired worldbuilding.
Gunpowder Moon follows Caden Dechert, chief of moon mining operations for the United States and former Marine, as he and his small team of engineers and miners uncover a murder mystery. It is the year 2072 and the climate crisis is in full swing. Decades before, a large methane bubble escaped the Pacific Ocean, with the United States feeling most of its effects. The last hope for humanity lies in helium-3, a fuel used in fusion reactors that is found in accessible quantities on the moon. China and the U.S. both attempt to stay out of each other’s way with a tense truce while vying for the precious resource. Unfortunately for Dechert, the first murder on the moon occurs under his watch. The murder has the potential to set off a chain of events that could plunge the nations of Earth into another dark age. Dechert and his team work to solve the mystery before the “forces that be” on Earth find a way to use it an excuse for war.
The aspect of Gunpowder Moon that grabbed me the most was the attention Pedreira pays to physics on the moon. He wastes no time in making sure the reader is aware of how hostile the moon is to human life. From the effects of the lower gravity to the abundance of fine granules that make up the moon’s surface that cause attrition to the complex machinery, Dechert and his crew have a lot to worry about. It really set the stage for me as a reader, highlighting what can and cannot happen if violence breaks out between individuals or separate moonbases. In addition, it spotlights the sheer amount of work that must be done in order to hold the moon at bay while the miners extract the necessary fuel to power Earth. I also appreciated that a lot of the rules were set in the beginning, providing the reader with knowledge that newcomers to the moon may overlook as the story progresses. It also circumvents the problem of breaking down an issue after it has occurred, while allowing the reader to feel engaged when things start to go wrong.
I also enjoyed the setting in terms of the historical context leading to the events of the book. The nations of the world are in recovery after a large and costly war, instigated by the effects of a rapidly changing climate and reduced access to cheap energy. While this setup was interesting, it did not feel fleshed out. Pedreira seemed to rely on projecting current international politics into the future, expecting the reader to fill in the blanks. Readers are treated to a greatly-diminished U. S. that is all too willing to instantly go to war in the Middle East. Their adversary feels more like a bogeyman than a nation with goals and aspirations. I do not doubt that these could be very realistic scenarios, but considering the book takes places fifty years from now, it was hard to accept that government and international relations would not experience the upheaval that the general populace did, especially when it seemed like the United States suffered catastrophic population loss. If there had been a clearer setup, or at least more exposition time on Earth highlighting the problems, it would have felt more dire and volatile. Instead, it seemed a tacked-on reason to place a story on the moon.
When it comes to exploring the characters, Pedreira does a decent job of placing the reader in Dechert’s shoes through a noir-style narration. It is easy to tell what he is thinking, and how he makes the decisions he does. While he is your typical gruff commander type, Dechert comes off as someone who cares deeply for his crew, while remaining uninvested in the Earth itself. His mild misanthropy was easy to relate to because of his devotion to making sure everyone on the moon station was constantly aware of the risks they posed to themselves and each other. My biggest problems with Dechert stemmed from his flashbacks from his time in the war. They were not necessarily bad, but they did not add anything, like showing him rethinking a decision or forcing him to confront something he had hidden deep down. The flashbacks mostly were there to remind you that Dechert was a Marine, he cared for his squad, and he killed people. They did not enhance his experience on the moon or reveal anything about his character to the reader that they could not already glean from his actions throughout the narrative
Unfortunately, Dechert was surrounded by stock characters who did not add much to the story beyond dialogue and tension with Dechert himself. Lane is the quintessential smart female engineer with a penchant for wanting to murder those who disturb her. Quarles is a snarky, younger, slacker genius who serves as Dechert’s delinquent but lovable foster son. Standard – yes that is the character’s actual name – is the typical corporate stooge, coming to inspect the station, making sure everything was on the up and up. The characters themselves were not bad, and their dialogue was largely enjoyable. There was clearly chemistry between everyone, but a lot of their quirks were handled through narration by Dechert. The reader is never treated to one of Lane’s death stares, or Quarles’ need to smoke pot. These are just traits that Dechert relates to the reader at odd times, ignoring the “show, don’t tell” rule. I never really felt like I got to know the people he cared so much about, only that he cared about his ragtag little group of misfits. I wish we encountered a little more of the characters outside of Dechert’s brain because they genuinely did seem fun, and possibly interesting. Instead, it felt like someone coming home from college trying to tell you about how cool and zany their new friends were.
If all these other parts of the book are a mixed bag, surely the plot itself was engaging enough to shepherd me to the end? Well, like most of the other things I have talked about, the story itself was also just on the cusp of being good. Pedreira managed to keep the pacing tight and fast. He did not waste time setting the rules of the world, and the murder quickly kicks the plot into high gear. The book never truly felt dull, and even though the flashbacks did not add anything, they felt appropriately placed. Tension built consistently, and I felt danger lurking at each turn as the moon’s environment and international tensions intertwined. However, the plot itself did not feel novel or exciting. The stakes were set high from the beginning, and never really grew. To be fair, it is hard to get any higher than globe-spanning warfare set off by a single murder on the moon, but it just fell flat for me. I am not a big fan of mysteries in general, so to center the fate of the world on solving a murder felt too big. And the reveal felt very “Saturday-morning cartoon” by way of Scooby Doo.
All in all, if you are just looking for a fun space romp that has a noir aesthetic to it, Gunpowder Moon scratches that itch. It has fun moments, and Pedreira really put some work into the moon-based setting. The addition of extreme caution to every decision the characters make supplemented the standard murder mystery storyline in a way that made it more appealing. Pedreira also shows a lot of potential in his writing abilities, especially with his dialogue and general structure of the story. I would not recommend it to avid readers of science fiction, but if you know someone who likes the idea of science and new rules attached to their mystery-thrillers, Gunpower Moon is a good start.
Rating: Gunpowder Moon – 6.0/10
