Livesuit is a 2024 science fiction novella by the writing duo James S. A. Corey (Daniel Abraham and Ty Franck). It is a standalone story set in the universe of their trilogy The Captive's War, which began with the novel The Mercy of Gods (2024).

The novella focuses on the technology of livesuits, which are biological armor systems that maintain a pilot's combat readiness over vast timescales.^[1] While it shares the same setting as the main trilogy, the story depicts a different faction of humanity and explores the deep history of the conflict between the Carryx and humanity.

Livesuit follows Kirin Foss, an EMT on a relatively peaceful human world, who enlists in the interplanetary war against the Carryx alongside his colleague Piotr for an eight-year tour of duty. Both are equipped with the epynomous livesuits: semibiological armor that enhances physical ability, permits operation in any environment including vacuum, and possesses remarkable regenerative properties, allowing the wearer to survive lethal injuries.

The narrative is structured nonlinearly. Over the course of several combat missions, Kirin and his unit experience significant time dilation from faster-than-light travel. A censored message from a former lover, Mina — now dead of old age while Kirin has aged less than four years — forces him to confront the true scale of his displacement from civilian life.

The story's central revelation unfolds when Kirin, examining a foot injury sustained in combat, discovers that his suit has replaced the foot and most of the leg with its own biological material. Scanning Piotr, who has communicated only by text since an early severe injury, he realizes that Piotr has long been dead — his body animated entirely by the suit. Kirin connects this with other soldiers who have undergone dramatic personality changes and realizes what Mina was attempting to warn him of: livesuits cannot be removed. They progressively incorporate themselves into the wearer's body, eventually subsuming it. The promised eight-year tour is a fabrication: no livesuit soldier ever returns home. The novella closes with Kirin wondering how long it will take for his suit to recognize that he has understood the truth and kill him.

Critics have noted that while The Mercy of Gods is a sociological study of captivity, Livesuit returns to the hard science fiction and military focus that characterized the authors' previous series, The Expanse, and its associated short fiction collected in Memory's Legion.^[2] The novella explores themes of transhumanism and the significant costs of survival in a hostile universe.

Reviewers have observed that the novella serves as a thematic companion to the main series by providing a perspective on the military forces that predate or exist outside the immediate context of the Carryx conquest seen in the first novel.^[3]

Published in October 2024, Livesuit was released to expand the lore of The Captive's War shortly after the debut of the first novel. The release coincided with the authors' broader expansion of the franchise, which includes a television adaptation being developed by their production company, Expanding Universe.^[4]

The authors have stated that the series is designed to explore xenobiology and the Great Lesson, a Carryx philosophy regarding the survival of civilizations.^[5]

Critical reception for the novella was generally positive, with particular praise for its gritty and visceral depiction of military life.^[6] Some analysis has focused on how the story functions as a narrative expansion that clarifies the technological stakes of the broader trilogy without requiring prior knowledge of the main novels.^[2]
