Zero-G / Samuel Lord Books in Order

The Zero G or Samuel Lord novels drop readers into the year 2050, when Earth’s orbit has become a crowded, contested neighborhood. The United States has turned its massive station, the Empyrean, into a kind of off world field office, and the FBI runs a small but crucial investigative unit there.

At the center of the series is Samuel Lord, an eighty year old former fighter pilot whose age has slowed him less than his superiors would like. He is stubborn, curious and dryly funny, and he treats the Empyrean like both a duty post and a small town where everyone’s business will eventually come across his desk. His Zero G agents come from different backgrounds and cultures, mirroring the mix of nations that have staked claims in orbit.

In Zero G, the unit has barely settled in when Dr May, a brilliant scientist based on the moon, arrives claiming that vital research has been stolen. Almost at the same time, a freak tsunami devastates the coast of Japan and a rival Chinese station falls unnervingly silent. Lord is forced to juggle diplomacy, crime scene work and emergency management while trying to decide whether he is looking at a natural disaster, an act of war or something stranger.

Zero G: Green Space deepens the sense that the real danger lies in the intersection of new technology and old rivalries. Experimental nanites meant to build structures in orbit begin behaving in terrifying ways, growing an out of control vine that threatens habitats and ships alike. Lord’s team races to understand what has gone wrong and who, human or otherwise, stands to profit from the chaos.

Tone wise, the series sits comfortably between a procedural and a space adventure. Shatner and his collaborator Jeff Rovin spend time on interviews, forensic work and chain of command, but they also lean into cinematic action sequences and big set pieces. The Empyrean itself feels like a character, from its spinning drums and greenhouses to the bars and corridors where agents blow off steam between crises.

Readers who enjoy near future science fiction grounded in recognizable institutions and personalities will find a lot to like here. The books are less about exotic aliens and more about how familiar human flaws play out once gravity, national borders and old assumptions no longer apply. Through Samuel Lord, the series keeps returning to a simple question: how do you keep doing the right thing when your world, and your own body, insist on reminding you how much time has already passed?
