Altered Carbon (Used Book) - Richard K. Morgan

Centuries from now, advances in technology have redefined life itself. A person's consciousness can now be stored in the brain and downloaded into a new body (or "sleeve"), making death nothing more than a minor blip on a screen. Onetime U.N. Envoy Takeshi Kovacs has been killed before, but his last death was particularly painful. Resleeved into a body in Bay City (formerly San Francisco), Kovacs is thrown into the dark heart of a shady, far-reaching conspiracy that is vicious even by the standards of a society tha treats existence as something that can be bought and sold. For Kovacs, the shell that blew a hole in his chest was only the beginning.
