Blade Runner

This 1982 tie-in reprint of Philip K. Dick's Do Androids Dream of Electric Sheep? gave the novel its widest audience, but the book is considerably different from Ridley Scott's film — and considerably richer. Dick's post-nuclear San Francisco is stranger, more philosophically restless, and more spiritually inflected than the movie's noir future, with the fictional religion of Mercerism adding a layer the film left behind entirely. The central question — what does empathy actually prove about humanity — is handled with real power. The honest caveats: this is adult science fiction with mature content including violence and sexual situations, it is not a film companion in any clean sense, and Dick's dense, episodic prose won't suit every reader. For serious science fiction readers, though, this is canonical work by one of the form's true masters.
