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.
