Blade Runner 2: The Edge of Human

Blade Runner 2: The Edge of Human (1988) is a novel by K. W. Jeter, and a continuation of both the film Blade Runner and the novel upon which it was based, Philip K. Dick's Do Androids Dream of Electric Sheep

The book continues the story of Rick Deckard. Beginning several months after the end of Blade Runner, the author attempts to resolve many of the differences between the movie and the novel. He also addresses at least one inconsistency to be found in the movie itself -- the question of the sixth replicant. Is Deckard a replicant after all?
