The final book in Philip K. Dick’s VALIS trilogy, The Transmigration of Timothy Archer brings the author’s search for the identity and nature of God to a close. The novel follows Bishop Timothy Archer as he travels to Israel, ostensibly to examine ancient scrolls bearing the words of Christ. But more importantly, this leads him to examine the decisions he made during his life and how they may have contributed to the suicides of his mistress and son.

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.

Glen Runciter runs a lucrative business - deploying his teams of anti-psychics to corporate clients who want privacy and security from psychic spies. But when he and his top team are ambushed by a rival, he is gravely injured and placed in "half-life," a dreamlike state of suspended animation. Soon, though, the surviving members of the team begin experiencing some strange phenomena, such as Runciter's face appearing on coins and the world seeming to move backward in time.

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.

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.

Jason Taverner - world-famous talk show host and man-about-town - wakes up one day to find that no one knows who he is - including the vast databases of the totalitarian government. And in a society where lack of identification is a crime, Taverner has no choice but to go on the run with a host of shady characters, including crooked cops and dealers of alien drugs. But do they know more than they are letting on? And just how can a person's identity be erased overnight?

Earth is trapped in the crossfire of an unwinnable war between two alien civilizations. Its leader is perpetually on the verge of death. And on top of that, a new drug has just entered circulation - a drug that haphazardly sends its users traveling through time. In an attempt to escape his doomed marriage, Dr. Eric Sweetscent becomes caught up in all of it. But he has questions: Is Earth on the right side of the war? Is he supposed to heal Earth’s leader or keep him sick? And can he change the harrowing future that the drug has shown him?

In Radio Free Albemuth, his last novel, Philip K. Dick morphed and recombined themes that had informed his fiction from A Scanner Darkly to VALIS and produced a wild, impassioned work that sounds like a visionary alternate history of the United States. Agonizingly suspenseful, darkly hilarious, and filled with enough conspiracy theories to thrill the most hardened paranoid, Radio Free Albemuth is proof of Dick's stature as our century's greatest science fiction writer.

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.

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".

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.

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.

The sky above the port was the colour of television, tuned to a dead channel. William Gibson revolutionised science fiction in his 1984 debut Neuromancer. The writer who gave us the matrix and coined the term 'cyberspace' produced a first novel that won the Hugo, Nebula and Philip K. Dick Awards, and lit the fuse on the cyberpunk movement.

"You will be called Anippe, daughter of the Nile. Do you like it?" Without waiting for a reply, she pulls me into her squishy, round tummy for a hug. I’m trying not to cry. Pharaoh's daughters don't cry. When we make our way down the tiled hall, I try to stop at ummi Kiya's chamber. I know her spirit has flown, yet I long for one more moment. Amenia pushes me past so I keep walking and don't look back. Like the waters of the Nile, I will flow.
