Morgan, Richard K.

Carl Marsalis, a genetically engineered soldier who was created by the United States military, escapes his exile on Mars and travels to Miami, where he intends on retiring, but instead is arrested and given the opportunity to avoid a jail sentence if he tracks down a serial killer fugitive, who was also created by the government.

Private eye Takeshi Kovacs goes AWOL with a band of resurrected soldiers of fortune to search for an ancient alien spacecraft and the highly advanced Martian race that landed it.

In the twenty-fifth century, advances in technology have redefined life itself and a person's consciousness can be stored in a cortical stack at the base of the brain and downloaded into a new body, allowing envoy Takeshi Kovacs to be able to find the men who killed him and seek revenge.
