Leviathan Falls
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.

James S. A. Corey
In the vast universe of modern science fiction, few names have reshaped the genre quite like James S. A. Corey—a pseudonym that conceals a powerful creative duo: Daniel Abraham and Ty Franck. Their collaboration gave birth to The Expanse, a sweeping space opera that redefined political intrigue, interplanetary tension, and character-driven storytelling on a galactic scale. With its gritty realism, moral complexity, and vast yet intimate scope, the series captured the imagination of a generation hungry for science fiction grounded not in fantasy, but in plausible futures.
The Expanse
Humanity has reached the stars—but it’s still haunted by its oldest problems.
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.
The Expanse consists of nine primary books, and includes one additional book that complement the series but is not considered mandatory reads and considered as a complete series. The current recommended reading order for the series is provided below.
