Blade Runner 4 by K.W. Jeter

Eye and Talon

In a gritty near-future continuation of the original story, an aging former blade runner is pulled back into a perilous investigation that further blurs the line between human and artificial life; as new conspiracies and shifting loyalties surface, he must confront haunting memories, questions of identity, and the moral cost of engineered beings while the city around him decays under corporate and social strain.
