Blade Runner 3 by K.W. Jeter

Replicant Night

A grim, noir continuation that plunges the former blade runner back into a dangerous world of replicant intrigue when a mystery surrounding illegal replicant technology and manipulated memories draws him into a labyrinth of corporate deceit and clandestine violence; as he pursues answers across a decaying, high-tech landscape he confronts haunting fragments of his past and is forced to face wrenching questions about identity, memory, and what separates human from machine.
