Mockingbird (A Steampunk Thriller)

The year is 2086, and the Earth is in ruins. After a long and destructive war between the humans and the androids, the last of humanity is a city built from the skeleton of post-apocalyptic Denver. The Fringe is the last city of the androids, who had finally gained their freedom after their rebellion. A desert separates the two civilizations, and no one has dared to confront each other in 50 years.
Until one day when an android called Prometheus shows up outside of the walls of Eden, with slight amnesia and a mission unwillingly programmed into him by a psychotic serial killer named Silas.
Throughout Prometheus' quest to foil Silas' evil agenda, he meets a human by the name of Eva Short, a hacker/programmer who wants vengeance on Silas for her brother's murder, as well as her best friend Augustus Quarterman.
Together, they will try to do the impossible, defeat Silas.
