4) Do Androids Dream of Electric Sheep? by Philip K. Dick

Earth is almost uninhabitable due to the effects of pollution and war. The wealthy have departed the planet, leaving the less fortunate, like Rick Deckard, to fend for themselves. During a particularly difficult assignment, Rick, who earns his livelihood by destroying rogue androids, is forced to consider his work and perhaps his identity. Perhaps the most comprehensible of Dick's many writings, Do Androids Dream of Electric Sheep? is an incredible book.
