Book Review: Cibola Burn by James S.A. Corey
The Story
Cibola Burn is the fourth thrilling entry in the acclaimed science fiction series, The Expanse, authored by James S.A. Corey. The book picks up after the events of Abaddon’s Gate, as humanity ventures beyond the Ring Gates to settle new worlds filled with untapped opportunity—and danger. The story centers on the planet of Ilus (also known as New Terra) where pioneering colonists from the Belt and corporate-backed settlers from Earth are locked in a bitter conflict over the rights to the land and its alien resources.
Standing in the middle of this escalating crisis is James Holden, who is once again called upon to mediate the situation before it boils over into full-scale violence. With his crew aboard the Rocinante, Holden is tasked by the United Nations to act as a neutral observer and negotiate peace. But as he learns more about the planet’s ancient, dormant alien technology—and the awakening of forces neither side understands—it becomes clear that the real threat may not be a political one at all.
Cibola Burn shifts from the political intrigue of previous entries in the series to a frontier-style tale full of resource-driven conflict, questions of colonization and ownership, and the haunting legacy of long-dead alien civilizations. It explores not just the external struggle for control of Ilus, but also the internal moral struggles of those at its center.
The Authors: James S.A. Corey
James S.A. Corey is the joint pen name of authors Daniel Abraham and Ty Franck. Abraham, celebrated for his work in fantasy with series like The Long Price Quartet, brings narrative elegance and character-driven storytelling to the duo. Franck, once a personal assistant to George R. R. Martin, developed the original concept for The Expanse universe as a roleplaying game. The fusion of their talents produced a compelling blend of engaging characters, hard science fiction, and thought-provoking politics.
As James S.A. Corey, the duo masterfully created a universe that feels both expansive and intimately human. Their ability to pivot styles—from political intrigue to space-frontier drama—allows the series to stay fresh and engaging with each book. Together, they have built The Expanse into one of the landmark sci-fi series of the 21st century, spawning a critically acclaimed television adaptation and earning comparisons to classic works like Babylon 5 and Dune.
Reflection and Insight
What makes Cibola Burn stand out within The Expanse series is its thematic depth. It’s not just about interstellar adventure or alien mysteries—it’s a focused look at the consequences of humanity’s expansion into the unknown. The planet Ilus serves as both a new frontier and a mirror to the colonial histories of Earth. The tension between displaced Belters and powerful corporate interests mirrors real-world historical conflicts, echoing instances of imperialism, displacement, and exploitation.
Holden’s character continues to evolve, portraying the ever-present moral conflict between pragmatism and idealism. His role as a mediator rather than a fighter adds complexity and weight to how challenges are resolved. And beyond the humans, the alien ruins influence the narrative with a sense of vast, unknowable history—reminding us that the universe is much older and stranger than we may ever be able to grasp.
With Cibola Burn, Corey shows again that science fiction can be more than just speculative—it can be profoundly human. The choices, mistakes, and courage on Ilus reflect values and questions we all grapple with, even here on Earth.
Happy reading, and I will see you in the next post!
