What is VALIS? This question is at the heart of Philip K. Dick's groundbreaking novel, the first book in his defining trilogy. When a beam of pink light begins giving a schizophrenic man named Horselover Fat (who just might also be known as Philip K. Dick) visions of an alternate Earth where the Roman Empire still reigns, he must decide whether he is crazy or whether a godlike entity is showing him the true nature of the world.

On Mars, the harsh climate could make any colonist turn to drugs to escape a dead-end existence. Especially when the drug is Can-D, which transports its users into the idyllic world of a Barbie-esque character named Perky Pat. When the mysterious Palmer Eldritch arrives with a new drug called Chew-Z, he offers a more addictive experience, one that might bring the user closer to God. But in a world where everyone is tripping, no promises can be taken at face value.

Substance D - otherwise known as Death - is the most dangerous drug ever to find its way on to the black market. It destroys the links between the brain's two hemispheres, leading first to disorentation and then to complete and irreversible brain damage. Bob Arctor, undercover narcotics agent, is trying to find a lead to the source of supply, but to pass as an addict he must become a user, and soon, without knowing what is happening to him, he is as dependent as any of the addicts he is monitoring.

On a ravaged Earth, fate and circumstances bring together a disparate group of characters, including a fascist with dreams of a coup, a composer who plays his instrument with his mind, a First Lady who calls all the shots, and the world’s last practicing therapist. And they all must contend with an underclass that is beginning to ask a few too many questions, aided by a man called Loony Luke and his very persuasive pet alien.

What happens after the bombs drop? This is the troubling question Philip K. Dick addresses with Dr. Bloodmoney, or How We Got Along After the Bomb. It is the story of a world reeling from the effects of nuclear annihilation and fallout, a world where mutated humans and animals are the norm, and the scattered survivors take comfort from a disc jockey endlessly circling the globe in a broken-down satellite.

On an arid Mars, local bigwigs compete with Earth-bound interlopers to buy up land before the Un develops it and its value skyrockets. Martian Union leader Arnie Kott has an ace up his sleeve, though: an autistic boy named Manfred who seems to have the ability to see the future. In the hopes of gaining an advantage on a Martian real estate deal, powerful people force Manfred to send them into the future, where they can learn about development plans.

Following an inexplicable urge, Ted Barton returns to his idyllic Virginia hometown for a vacation, but when he gets there, he is shocked to discover that the town has utterly changed. The stores and houses are all different and he doesn't recognize anybody. The mystery deepens when he checks the town's historical records...and reads that he died nearly twenty years earlier.

In the future, most of humanity lives in massive underground bunkers, producing weapons for the nuclear war they’ve fled. Constantly bombarded by patriotic propaganda, the citizens of these industrial anthills believe they are waiting for the day when the war will be over and they can return above ground. But when Nick St. James, president of one anthill, makes an unauthorized trip to the surface, what he finds is more shocking than anything he could imagine.

When a routine tour of a particle accelerator goes awry, Jack Hamilton and the rest of his tour group find themselves in a world ruled by Old Testament morality, where the smallest infraction can bring about a plague of locusts. Escape from that world is not the end, though, as they plunge into a Communist dystopia and a world where everything is an enemy. Philip K. Dick was aggressively individualistic, and no worldview is safe from his acerbic and hilarious takedowns.

The King of the Elves is the opening installment of a uniform, five-volume edition of The Collected Stories of Philip K. Dick, expanded from the previous Collected Stories set to incorporate new story notes, and two added tales, one previously unpublished, and one uncollected.

Ragle Gumm has a unique job: Every day he wins a newspaper contest. And when he isn’t consulting his charts and tables, he enjoys his life in a small town, in 1959. At least, that’s what he thinks. But then strange things start happening. He finds a phone book where all the numbers have been disconnected, and a magazine article about a famous starlet named Marilyn Monroe, whom he’s never heard of. Plus, everyday objects are beginning to disappear and are replaced by strips of paper with words written on them, like "bowl of flowers" and "soft-drink stand".

Journalist Mike Watson and his wife, Phyllis, trace it back to the strange showering lights they noticed on the final day of their honeymoon cruise; lights which appeared to land and disappear into the water. Reports mount of similar sightings all over the world. Governments embark on missions to investigate the sea, but ships disappear and diving crews never return to the surface. Something deep in the ocean does not want to be disturbed.

The Covenant mission is the most ambitious endeavor in the history of Weyland-Yutani. A ship bound for Origae-6, carrying 2,000 colonists beyond the limits of known space, this is a make-or-break investment for the corporation - and for the future of all mankind. Yet there are those who would die to stop the mission. As the colony ship hovers in Earth orbit, several violent events reveal a deadly conspiracy to sabotage the launch.

This novel, Dick said, is about Leo Runcible, "a brilliant, civic minded liberal Jew living in a rural WASP town in Marin County, California." Runcible, a real estate agent involved in a local battle with a neighbor, finds what look like Neanderthal bones in Marin and dreams of rising real estate prices because of the publicity. But it turns out that the remains are more recent, the result of an environmental problem polluting the local water supply.

Finnegans Wake, the greatest avant-garde novel of all time, was first published 70 years ago - and people are still trying to work out what it is about. There is Humphrey Chimpden Earwicker - aka HCE (Here Comes Everyone) - and Anna Livia Plurabelle, but also Finnegan the hod carrier (or was he a giant?), whose wake is the subject of the book. This is a masterly reading of the abridged version, with copious notes aiding comprehension.
