/lit/ - Literature

I've started actually reading sci-fi, and so far i've gotten through pic related and an anthology from the fifties called Horses asteroid (pretty good in some places, a lot of fun anachronism like 'Android' being used to describe a human clone and helicopters being portrayed as the coolest shit ever), Are there any other books that have characters like John Isidore? I only knew about the book from knowing blade runner was based on it, but i really don't understand how it cut him, he's the heart! Just a fundamentally decent person living in a very horrible world, the kinda guy who'd give up his last cube of margerine as a house warming gift.
