A Mars science fiction mystery
What happens when the safest colony on Mars stops feeling safe?
Beneath the harsh crimson sands of Mars lies Port Hope, humanity's first true colony beyond Earth: an underground marvel forged by necessity, resilience and unwavering ambition. Guided by the enigmatic President Edward Moss, the colony thrives, built on discipline, unity and a dream that Mars will be humanity's final home, while Earth fades into myth.
But not all is as it seems.
Behind polished domes and precisely engineered order, truths are buried: secrets powerful enough to reshape humanity's future. As murmurs of dissent grow and shadows of the past begin to stir, one question becomes inescapable: what price must be paid to protect a dream?
A thrilling blend of speculative science, political intrigue and philosophical depth, Republic of Mars challenges everything you think you know about survival, destiny and truth. In a world where history is written beneath red dust, can hope still find a voice?
Some truths are better left buried.
Inside the book
A fast-paced detective plot
A high-profile murder, a colony that cannot afford the truth, and an investigation that keeps the pages turning from chapter one.
A bonus chapter on Port Hope’s engineering
A technical appendix on the design of the underground habitat, written for readers who love the engineering as much as the story.
One of the new books about Mars worth reading
Most books about Mars focus on getting there. Republic of Mars asks what happens after: who holds power in a sealed colony, what gets erased from the record, and what freedom means when order is the only law.
For hard science fiction readers
Speculative but grounded: every system in Port Hope is built on credible physics and engineering.
For fans of a murder mystery on Mars
A whodunit set where there is nowhere to run and every record can be rewritten.
For readers curious about living underground on Mars
Port Hope is buried two hundred meters below the surface. The novel imagines what daily life, and power, look like down there.
