In the eternal darkness of the moon, something is calling.
When NASA’s Sentinel I satellite detects an impossible reflection and a mysterious signal from Shackleton Crater, the world is thrown into chaos. The discovery points to one chilling truth: an alien artifact lies hidden beneath the lunar surface—and it wants to be found. As China scrambles to exploit the revelation, a new moon race ignites, pushing humanity to the brink.
Thrust into the center of the storm, NASA astronaut Charlie Reid must navigate a volatile mission where science, survival, and military might collide. With the fate of humanity hanging in the balance, the question remains: what will they find—and will we survive it?
The race for the future has begun. And the prize may cost us everything.
Joshua T. Calvert has traveled the world--on foot, by Jeep, by bicycle, by motorcycle, and lots of other ways besides. As you might imagine, he's seen many things most people never see - including an Iranian prison cell, from the inside! In Kyrgyzstan, he fared slightly better, narrowly avoiding being kidnapped for ransom. Skydiver, scuba diver, martial artist, adventurer - his goal is to experience everything possible, and then make it real to you in his books. And he's made a good run of it so far: in the Philippines, he did police training on multiple types of firearms (despite being no fan of guns himself); dove in Asian waters among sharks and shipwrecks; and patrolled with Sumatran jungle rangers.
That's what defines Calvert's approach to method writing: pushing himself beyond his own limits, to experience first-hand what his characters experience, to make your immersion in his stories as deep as it can be.
For Ganymede Rises, after a slight detour with some smugglers in the deserts of Uzbekistan and the steppes of Mongolia, he traveled by dogsled and snowshoe to the Arctic Circle to experience first-hand what it's like to be utterly isolated in the coldest place on Earth. For his book The Fossil, he sat with professional pilots in flight simulators for Airbus A320 and Boeing 737 aircraft to learn what it's like to fly a passenger jet. His latest adventure: a parabolic flight with European Space Agency astronauts, to experience zero-gravity. All so he can describe it to you, in his own words.
This story starts just a bit slowly but hang in there as the story builds. Mr. Calvert has impressive knowledge of space programs and the way things are calculated re distances and orbits. Much deeper than I anticipated. Enjoy!
The Shackleton Signal is a sci-fi thriller revolving around a mysterious signal coming from a crater on the moon. Nothing is as it seems, with interference by Space Force to cover up a massive screw up. The book ends on n amazingly positive note that I wish we would see in real life. Hard sci-fi thrillers are among the most difficult to write, but Calvert is a narrative master and the book unfolds at a perfect pace with characters, dialog and plot exactly how they should be written! I recommend this book not only to sci-fi nerds, but for anyone interested in excellent, fast paced writing and unbelievable feats becoming entirely believable. 5/5 stars, easily one of the best sci-fi books of 2024!
The Shackleton Signal by Joshua Calvert could be described as both a mystery as well as a “hard� sci-fi adventure. The pacing and the “hard� science descriptions certainly make this novel exciting and believable � There’s good explanations about why it’s necessary to re-engineer our moon spacecraft and all the technicalities necessary to accurately place a spacecraft in lunar orbit. There is action both in space and on the ground, as dual mysteries are seeking to be solved. Throughout much of the story, the focus seemed to be on the alien signal, the object, and its origins, and then everything changes in an instant when all is revealed.
I just couldn't slog on. I saw first twist coming a mile away. If you've even read or seen Sagan's *Contact* then at least the first third reads like a mild knock-off. But I just wasn't hooked. I felt myself putting it down more than picking it up.

“First the wrinkles on her forehead deepened into deep canyons�.
A fair idea with poor execution and editing. More of a primer on large US state institutions and their inter-relationships than a first contact sci-fi novel.
A signal is detected from the Shackleton crater on the moon which is at the South Pole end of the moon. The US and China both plan on sending up a team to investigate but who will get there first? What exactly is sending the signal? Meanwhile a security analyst is finding that things may not be as they seem... This book describes the race between the two nations (told from the US viewpoint) and provides a high level of scientific detail about the problems of space travel and reaching, let alone walking , on the moon. There is much intrigue, suspense, action, surprises, and twists in this enlightening tale as both the Chinese kaikonauts and US astronauts strive to reach the source first...

This would have been an enjoyable book, but despite being billed as hard sci-fi, it has a LOT of factual errors. Too many to list, but here are three examples:
***Minor Spoilers Below***
There are no such words as "periselenium" and "aposelenium" in the English language. In lunar orbit terminology, the lowest point of the orbit is called the perilune (or periselene), and the highest point is called the apolune (or aposelene). "Selenium" is an element with the symbol Se and atomic number 34.
At one point, a character is described as a "Navy Colonel." No such thing - the equivalent rank is a Captain. As a former Naval officer, I almost quit right there. Btw, anyone who thinks a officer of any rank would regard an NCO as "only a Master Sergeant" clearly has never been in the military.
Even near the poles, the temperatures on the lunar surface do not fluctuate from hot to cold "every few hours" � it's more like every 14 days.
There's a long description of "steam" being released from cryogenic fluids. Sorry, but no � steam is hot water vapor, while fog and clouds are cold water vapor. Venting cryogenic liquids generates clouds of very cold fog.
Before a launch, he mentions "refueling" the booster. This would actually be fueling.
Raptor engines run on liquid Methane fuel and liquid Oxygen as the oxidizer. Referring to them both as "fuels" is incorrect.
There are *many* more examples, but you get the idea�
The story is about a strange signal emanating from the Shackleton crater on the south pole of the moon. Both the Americans and Chinese go to investigate. It was reminiscent of the space race during the Kennedy years between the US and Russia. This time the race was about who would uncover the origin and nature of the strange signal. Would it be alien life? Would it be the Americans or the Chinese to get their first to take credit for the discovery, and to determine whether it was truly alien life. Both the Chinese and American astronauts were in fierce competition with each other that led to quite a bit of action and drama. But in the end, only two astronauts left standing: one Chinese, and one American team up together to get back home to mother earth. Plus, throughout the book there was a secondary plot involving investigation into corrupt American military space force officers attempting to hide some secret aspects of the space mission. The book was well written. It had much intrigue, action, and drama. It was hard science fiction not involving super advanced technology, but rather more or less technology that we have today. I highly recommend this book.
The book has an enticing premise that suffers from a lack of research, notably involving the US military and more generally the aerospace industry. The book presents itself as "hard science fiction" and if so, it barely qualifies as such. While the author did create some good suspense with the story in the beginning, it fell flat in the last third.
The book overview states: The discovery points to one chilling truth: an alien artifact lies hidden beneath the lunar surface—and it wants to be found.
However, this is not a first contact story, or even a "discovered alien tech" story, as there are no aliens or alien artifacts on the moon. The main conflict occurs when it's discovered not to be alien. It's more a political / spy thriller, but there, too only marginally. I didn't appreciate the bait and switch. I was just disappointed in this book in general.

It’s easy to suspend a reader’s disbelief as you read Calvert’s book. Post Cold War politics and military rivalry both play a part in this technically accurate story (as near as this retired Silicon Valley analog IC engineer and space history nerd can tell). Is there really water ice in perpetually dark craters at the Moon’s South Pole? Will there really be military conflict in space? Are rogue military elements waiting to take charge if they think civilian agencies are screwing up by the numbers?
No one can be sure about some of it, at least not until the next manned lunar missions. In the meantime, what Joshua Calvert speculates here feels entirely possible.
Definitely worth much more than the price of admission.
Prosaic is the word that comes to mind � maybe even pedestrian. This “Hard SF Thriller� (whatever that signifies) begins with an interesting premise: the discovery of a “potentially extraterrestrial signal from the Shackleton Crater� (p31) � an unusually deep crater at the Moon’s south pole where, literally, “the sun never shines,� (p60), which adds to the mystery. Despite some know-it-all pointing out that “Only twelve people have ever set foot on the moon� (p163), the signal sets off a virtual land rush as China and the U.S. space programs both race to get missions to the Shackleton first. THE SHACKLETON SIGNAL should have been exciting, but the story plodded and the characters seemed to have reported for duty straight from a mediocre streaming mini-series.
The one item that struck me about this book was the incredible attention to detail combined with the machinations of the characters. In this age of zap bang pow of Galactic conflicts and star wandering, the fact that we re still fairly earthbound and haven't even been back to the moon yet. To some who say we have issues and challenges here on Earth and we should address them. My response would be to say the same to any child who makes a mess: " YOU messed it up-----Go Un- mess it!!!!! In truth I haven't encountered a book as well written as this since NO MAN'S WORLD, or THE CAPE by Martin Caidin. Very well done Sir. Bill Hodges
Meh. Stereotypical story about the US and China racing to the moon for a mysterious reason. Plenty of military bravado and covert teams as well as "patriotic" pride. The storyline was predictable and the actions of most pretty absurd. And just because some takes place on the moon, does it automatically become Sci-Fi?
I wasn't a fan of most of the characters (a grown-ass man doesn't know anything about China?) and each played a singular role without any depth. And how many intelligent people can be described as having hawk-like intelligence? Or sharp as a hawk? Or eyes of a hawk?
The science fiction thriller captivated readers with its dynamic narrative and pulse-pounding action sequences. The protagonists were expertly crafted, each bringing depth and complexity to the storyline. Unexpected plot twists and revelations kept the audience engaged throughout the novel. The unique narrative structure, which seamlessly transitioned between terrestrial and extraterrestrial settings, created a rich and multifaceted storytelling experience. This dual-perspective approach added layers of intrigue and complexity, allowing readers to explore the story from different vantage points and enhancing the overall dramatic tension of the narrative.
Thank you Mr. Calvert for making a truly enjoyable story
1st I would like to say it is a distinct pleasure to read a stand-alone book, That you don't have to wait 3 months for the second part to be released then 8 months for the 3rd book to come out, then Then the beginning of next year for the 4th book! And the characters were so believable, and that's saying something! I don't know physics but I was happy to learn, without being overburdened with useless knowledge that adds nothing to the story. The ending was better than I hoped it would be. Truly a good read. Highly recommend.
This is an excellent book that I truly enjoyed reading. The action was superb and very technically realistic (from a non-astronaut/-taikonaut POV). But even better were the social and human interactions, and the astute observations about the folly of our still-tribal approach to international & domestic politics. As so well articulated by Joshua, we all need to learn the lessons that many spacefarers & others extol: we are all one people & one race (human) and earth is our only home.
Enjoyed this story as it mixed a space tale with a political and sinister plot on earth. There are so many stories around of American secret agencies with their own agenda's. You have to worry that it could be happening in reality? I also sincerely doubt the American and Chinese governing bodies could come together because of the tale here. They both seem to be so entrenched in their own view, it for an sound possible for them to reconcile in any shape or form. A definite recommended for me for the unusual story and quality of writing.
What do you do with a secret that would cause WWIII if revealed? How much government subversion and how many deaths will there be to keep it secret? Joshua Calvert weaves an intricate story of one woman's battle to discover the secret and one astronaut's conflict with the requirements of duty, patriotism, friendship, survival and truth. If you enjoy realistic science and the power struggle with the deep state, you will enjoy this novel. Just be prepared for a few surprises and joining in the main characters' struggles.
I really liked the first like 75% of the book which essentially revolves around the discovery of something odd on the moon and a subsequent space race between the US and Chinese.
However, the Big Reveal and the rest of the book that follows I felt fell a bit flat with some forced messages. It wasn’t like out of the realm of what I expected it just wasn’t what I wanted I guess. It was also funny how SpaceX and Musk were brought up and the author was definitely a fan. There were lines about his extreme attention to security and things like that. Did not hold up to present day lol.
Technically very good and a great character mastery as expected. Seems unnecessarily anti American and anti military for a space adventure but I guess that appeals to the younger readers unfortunately. I wish we and China could find more common interests and agree but we both have a lot to change first. Unlike countries like Japan England and France the USA has not fought brutal wars with China and the animosity is only based on propaganda and financial competition so maybe there is hope.
I found the premise of this book very interesting. Some of the characters were also interesting. It is obvious that the author was never in the military or did any research about the military. Things like a navel colonel, specialist ranks in the air force, Ensign's as gate guards at an air force base etc . If the military is going to be a major part of your story you should get the details right! Otherwise I found it to be entertaining
I appreciate that writing a novel is a difficult thing. This one feels like it needed another draft or two before it should have been released. The plot was patchy and predictable, the characters pretty one dimensional and undeveloped, and the dialogue usually left me acutely aware that I was reading someone’s writing rather than being transported into the story.
The book was enjoyable and easy to read. There was a lot of technical jargon and explanation of modern space faring. But that did not impede the enjoyment of the plot or weigh down the readability.
I appreciated the inclusion of contemporary sociopolitical entities and the relative real world issues.
The story held action, espionage, and drama suitable for a film.
Discovery of a mysterious signal coming from the far side of the moon spurs the USA and China into race to investigate.
Science fiction with an emphasis on the science, Calvert's novel bears comparison with the works of Andy Weir, although doesn't quite hit those heights. Occasionally dogged by clumsy exposition, The Shackleton Signal is a good read, not least for the fanciful notion of a helpful and generous Elon Musk.
It is sad that the author Stephen King is rough on his characters. Well Joshua T Calvert is just like that. I am glad I don't live in his world as a main character but it is quite interesting to follow them and see how they survive all of that. Great story.
Although going into some detail, scientific and otherwise, that could have dragged, it didn’t. It was a real page turner. Of course, not an original concept, but a very entertaining treatment. One can only hope that there are such heroes, both here on earth and on the moon!
A nice mix of hard science and fiction. Really good character development. Definitely believable and sympathetic. Believable villains too. And the plot? You don’t have to be too paranoid or a very big conspiracy theorist to believe that it could definitely happen. The last chapter is as tasty as it gets in this genre. Masterfully crafted.
This was a fun read, but a very light one. The writing at times was awkward, and the characters were shallow and not particularly well drawn. The plot line held no real surprises, save one, and the story telling more than a bit derivative. That said, it went down easily enough to a satisfying, if entirely predictable, conclusion.
Characters are well developed - tangibly real, not just cardboard cutouts. Great testament to what the dream of a unified planet, pushing into space together, could be, and the risks to humanity inherent in placing unfettered power in the hands of a power-drunk few, devoid of morality...
