Do Androids Dream of Electric Sheep?

Another book I've picked up because of it's interesting title. I'm a good example of someone who judges a book by its cover xD

Synopsis from Amazon:

By 2021, the World War had killed millions, driving entire species into extinction and sending mankind off-planet. Those who remained coveted any living creature, and for people who couldn't afford one, companies built incredibly realistic simulacrae: horses, birds, cats, sheep. . . They even built humans.
Emigrées to Mars received androids so sophisticated it was impossible to tell them from true men or women. Fearful of the havoc these artificial humans could wreak, the government banned them from Earth. But when androids didn't want to be identified, they just blended in.
Rick Deckard was an officially sanctioned bounty hunter whose job was to find rogue androids, and to retire them. But cornered, androids tended to fight back, with deadly results.

It's a cool story haha, I can see it being a good book to analysis in English. There's multiple symbols and themes, two of which being empathy as a uniquely human trait and to a lesser extent the slavery of androids. Then there's the electric animals, which I think closely relates to fake designer goods in our world.

The cover touts this book as "a kind of pulp-fiction, kafka, a prophet", which I don't really get. Then again I don't get why Pulp Fiction is so great nor have I read Kafka. This book is the source material for Blade Runner, which I haven't watched. Perhaps watching the movie beforehand would have increased my appreciation of the book.
