A Scanner Darkly by Philip K. Dick is a drug induced, comical, dialogue based roughly on the personal experiences and made-up scenarios of science fiction writer Philip K. Dick. Full of comedy and bleak day-to-day occurrences of an addict, it gives true insight of those who have delved too deep into the murky realm of drugs and "Substance D." Not sure whether to laugh or cry at times, the book takes the reader into a world where the government's authority and people's paranoia runs rampant.
