Altered Carbon

Altered Carbon is a 2002 cyberpunk novel set in a future where human consciousness can be transferred between bodies (called "sleeves"). The protagonist, Takeshi Kovacs, is a former soldier and mercenary who is brought back from cryogenic storage to solve a wealthy man's murder. The narrative explores themes of identity, mortality, inequality, and what it means to be human when consciousness becomes transferable and bodies become commodities.

The novel is structured as a noir detective story within a richly detailed cyberpunk world featuring advanced technology, corporate dominance, and social stratification. Kovacs navigates a complex investigation involving virtual reality, artificial intelligences, and the moral implications of consciousness technology. The work examines how immortality for the wealthy exacerbates class divisions and raises philosophical questions about personal identity and continuity of self.

Altered Carbon became influential in contemporary science fiction, spawning two sequels (Broken Angels and Woken Furies) and a Netflix adaptation series (2018–2020). The novel is credited with revitalizing cyberpunk as a genre and influencing subsequent discussions about consciousness, technology, and transhumanism in speculative fiction.
