Altered Carbon by Richard Morgan

These excerpts chronicle the journey of Takeshi Kovacs, an Envoy re-sleeved into a new body (Elias Ryker's) and leased from storage to investigate the alleged murder of the incredibly wealthy and powerful Laurens Bancroft, a "Meth" (Methuselah, implying extreme longevity). The narrative follows Kovacs as he navigates a corrupt and technologically advanced society in Bay City, Earth, working for Bancroft while facing hostility from the police, particularly Detective Lieutenant Kristin Ortega, who views the case as a clear suicide. Kovacs's investigation uncovers a complex conspiracy, involving Reileen Kawahara, who is ultimately revealed to be manipulating events to force Bancroft's suicide to prevent a blackmail scheme and protect her illicit business on Head in the Clouds, a high-end aerial brothel. The core of the story revolves around themes of immortality, identity, corporate corruption, and the violent undercurrents of this future society, concluding with Kovacs confronting Kawahara and escaping the morally compromised situation to return to his homeworld.
