Foundation by Isaac Asimov

For twelve thousand years the Galactic Empire has ruled supreme. Now it is dying. Only Hari Seldon, creator of the revolutionary science of psychohistory, can see into the future—a dark age of ignorance, barbarism, and warfare that will last thirty thousand years. To preserve knowledge and save humanity, Seldon gathers the best minds in the Empire—both scientists and scholars—and brings them to a bleak planet at the edge of the galaxy to serve as a beacon of hope for future generations. He calls this sanctuary the Foundation.
 
But soon the fledgling Foundation finds itself at the mercy of corrupt warlords rising in the wake of the receding Empire. And mankind’s last best hope is faced with an agonizing choice: submit to the barbarians and live as slaves—or take a stand for freedom and risk total destruction.

I read this in the 70's and I enjoyed it again as much as the first time.  5/5 stars, highly recommended.

A Scanner Darkly by Philip K. Dick

Bob Arctor is a dealer of the lethally addictive drug Substance D. Fred is the police agent assigned to tail and eventually bust him. To do so, Fred takes on the identity of a drug dealer named Bob Arctor. And since Substance D, which Arctor takes in massive doses, gradually splits the user's brain into two distinct, combative entities, Fred doesn't realize he is narcing on himself.

Caustically funny, eerily accurate in its depiction of junkies, scam artists, and the walking brain-dead, Philip K. Dick's industrial-grade stress test of identity is as unnerving as it is enthralling.

The Game Players of Titan by Philip K. Dick

Years ago, Earth and Titan fought a war and Earth lost. The planet was irradiated and most of the surviving population is sterile. The few survivors play an intricate and unending game called Bluff at the behest of the slug-like aliens who rule the planet. At stake in the game are two very important commodities: land and spouses. Pete Garden just lost his wife and Berkeley, California, but he has a plan to win them back. That is, if he isn’t derailed by aliens, psychic traitors, or his new wife.

The Game-Players of Titan is both satire and adventure, examining the ties that bind people together and the maddening peccadilloes of bureaucracy, whether the bureaucrats are humans or alien slugs.

The Three Stigmata of Palmer Eldritch by Philip K. Dick

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.

This Nebula Award nominee is one of Philip K. Dick's enduring classics, at once a deep character study, a dark mystery, and a tightrope walk along the edge of reality and illusion.

This is a mind-blowing book; a true work of art.  Highly recommended, 5/5 stars.

The Stars, My Destination by Alfred Bester

Marooned in outer space after an attack on his ship, Nomad, Gulliver Foyle lives to obsessively pursue the crew of a rescue vessel that had intended to leave him to die.

When it comes to pop culture, Alfred Bester (1913-1987) is something of an unsung hero. He wrote radio scripts, screenplays, and comic books (in which capacity he created the original Green Lantern Oath). But Bester is best known for his science-fiction novels, and The Stars My Destination may be his finest creation. With its sly potshotting at corporate skullduggery, The Stars My Destination seems utterly contemporary, and has maintained its status as an underground classic for fifty years. (Bester fans should also note that iPicturebooks has reprinted The Demolished Man, which won the very first Hugo Award in 1953.)

Alfred Bester was among the first important authors of contemporary science fiction. His passionate novels of worldly adventure, high intellect, and tremendous verve, The Stars My Destination and the Hugo Award winning The Demolished Man, established Bester as a s.f. grandmaster, a reputation that was ratified by the Science Fiction Writers of America shortly before his death. Bester also was an acclaimed journalist for Holiday magazine, a reviewer for the Magazine of Fantasy and Science Fiction and even a writer for Superman.

Crosstalk by Connie Willis

In the not-too-distant future, a simple outpatient procedure to increase empathy between romantic partners has become all the rage. And Briddey Flannigan is delighted when her boyfriend, Trent, suggests undergoing the operation prior to a marriage proposal—to enjoy better emotional connection and a perfect relationship with complete communication and understanding. But things don’t quite work out as planned, and Briddey finds herself connected to someone else entirely—in a way far beyond what she signed up for.

It is almost more than she can handle—especially when the stress of managing her all-too-eager-to-communicate-at-all-times family is already burdening her brain. But that’s only the beginning. As things go from bad to worse, she begins to see the dark side of too much information, and to realize that love—and communication—are far more complicated than she ever imagined.

The best book I've read this year.  ******* of 5 stars!

Martian Time-Slip by Philip K. Dick

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. But is Manfred sending them to the real future or one colored by his own dark and paranoid filter? As the time travelers are drawn into Manfred's dark worldview in both the future and present, the cost of doing business may drive them all insane.

A classic. The first I'm going to read of Dick's collection. 5/5 stars.
