The Expanse: Leviathan Falls

Yes, Leviathan Falls is the ninth and final main-series novel in The Expanse, concluding the story arc that began with Leviathan Wakes in 2011. While there are additional novellas and short stories set in the same universe, the core nine-book series reaches its definitive ending with this novel.

Leviathan Falls was published in 2021 by Orbit Books. It arrived approximately ten years after the series debut, wrapping up a saga that had also been adapted into the popular television series on Amazon Prime Video.

James S.A. Corey is the pen name used by co-authors Daniel Abraham and Ty Franck, who collaborated on all nine novels in The Expanse series. The name itself is derived from their respective middle names (Corey) and initials, and the duo worked closely together on every aspect of the series' plotting and prose.

Leviathan Falls resolves the major plot threads involving the Laconian Empire, the protomolecule's mysterious creators, and the fate of characters like James Holden and Naomi Nagata. Many readers consider it a strong conclusion to the series, though some story elements remain open-ended in a way consistent with the series' themes about the unknowable scale of cosmic history.
