Ubik - Philip K. Dick

"An accident has occurred. Joe Chip and his colleagues-all but one of
them-have narrowly escaped an explosion at a moon base. Or is it the
other way round? Did Joe and the others die, and did the one fatality,
Glen Runciter, actually survive? . . . From the stuff of space opera,
Dick spins a deeply unsettling existential horror story, a nightmare
you'll never be sure you've woken up from."-Lev Grossman, Time

In 1974, Philip K. Dick was commissioned to write a screenplay based on his novel Ubik.
The film was eventually scrapped, but the screenplay was saved and
later published in 1985. Featuring scenes that are not in the book and a
surreal playfulness-the style of the writing goes back in time just
like the technology in the book's dreamworld-this screenplay is the only
one Dick wrote and features his signature mix of paranoia, humor, and
big-idea philosophy.
