One of the greatest writers in science fiction history, Philip K.Dick is mostly remembered for such works as Blade Runner, Minority Report, and Total Recall.His dark, fascinating work centred on alternate universes and shifting realities in worlds often governed by monopolistic corporations and authoritarian governments.His own life story seems a tussle with reality, cycling through five marriages and becoming increasingly disjointed with fits of paranoia and hallucinations fuelled by abuse of drugs meant to stabilise him.His dramatic story is presented unvarnished in this biography.
