The final novel in The Expanse series.
Set in the distant future in an inhabited solar system split between three major factions (Earth, Mars, and the Asteroid Belt / Outer planets), Leviathan Wakes follows the crew of an ice hauler — captain James Holden, XO Naomi Nagata, pilot Alex Kamal, and engineer Amos Burton — after they encounter a ship in distress. A private company unleashes an alien substance known as the Protomolecule, plunging the system’s various factions into a major conflict as they vie for power.
The substance is essentially a technology that can replicate itself and manipulate matter, and it eventually links our solar system to a vast network of other gates and habitable planets, allowing humanity to expand into the galaxy. In the latest pair of novels, Abraham and Franck jump decades into the future, where a lost Martian task force returns — having used the Protomolecule to create some advanced technologies and set up a fascist civilization — and are bent on creating an interstellar empire.
The series
Humanity has reached the stars—but it’s still haunted by its oldest problems.
Read full series description
The Expanse begins not with a heroic mission or utopian dream, but with a missing girl and a mystery that pulls at the fragile threads of a solar system on the brink. Mars, Earth, and the scattered colonies of the Belt live in uneasy balance, each burdened by political tension, economic disparity, and centuries of mistrust. And then something ancient awakens.
What sets this science fiction epic apart isn’t just the scale—though it spans planets, factions, and eras—it’s the people caught in the chaos. A haunted ship’s captain with a stubborn moral compass. A foul-mouthed politician willing to burn worlds to save her own. A Belter detective chasing ghosts through dust and vacuum. Their stories intertwine not because fate demands it, but because the system they inhabit is collapsing—and they’re just awake enough to notice.
The world-building is dense and lived-in, with asteroid stations that feel rusted and claustrophobic, Martian warships that hum with quiet threat, and alien technologies that refuse to be understood. Yet amid the cosmic scope, the emotional core always stays human. The writing captures the intimacy of fear, loyalty, and hard choices, even when the stakes are planetary.
Adapted into a critically acclaimed television series, The Expanse has become a touchstone for modern space opera—not by echoing the past, but by carving its own orbit through the genre. It’s science fiction where the future looks eerily familiar, and the real alien threat might not be from beyond the stars, but from what we carry with us into them.
