Blade Runner/The Edge of Human

Blade Runner 2: The Edge of Human (1988) by K. W. Jeter, 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 upon which it was based, Do Androids Dream of Electric Sheep? 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?
