Davis has just lost his wife, Rachel. Bewildered and alone, he downloads an app that promises to restore a bit of her to ease his grief and loneliness. He uploads their chat history to train the app’s AI on her thoughts, her style of writing, and their dynamic. Soon, he begins receiving texts from his beloved. They resume their relationship in the virtual world where it left off in the physical world.

Anyone who’s been in a long-distance relationship knows how frequent, intimate communication stokes the desire to see and be with the beloved. As Davis’ desire grows, the AI company behind the app begins to roll out new features. Would you like to see Rachel? Upload some photos, and we’ll show you new ones of her in exotic places.

Dr. Bloodmoney, published in 1965, takes place in the imagined future of 1980s California. The book opens in Berkeley in 1981, where Stuart McConchie works as a television salesman. McConchie watches a familiar-looking man whose face he can’t place walk into the psychiatric office of Dr. Standstill, across the street.

The patient, we soon learn, is Dr. Bruno Bluthgeld, a former physics professor at Berkeley and researcher at the Livermore lab whom most people blame for an ill-conceived 1972 nuclear test that exposed huge numbers of Americans to toxic radiation. One effect of the radiation is a spike in phocomelia, a condition in which children are born with stunted, fin-like arms and legs. (When Dick wrote the book in 1963, there was an explosion in phocomelic births due to the drug Thalidomide being prescribed as a treatment for morning sickness in pregnant women.)

Note: This review contains spoilers, outlining most of the plot. But also note that Permutation City is not genre fiction, so the plot is not the point. The value of this book lies in its deep exploration of ideas.

Greg Egan’s 1994 novel Permutation City is, first and foremost, the product of a brilliant mind. The story opens, more or less, around the year 2050. The rich have taken to scanning their minds before death and then running their digital consciousness as “Copies” inside of computer-generated virtual realities. They can edit their scans as they please, so they are young and vigorous in the virtual world, and they can even edit out the less pleasant parts of their psyches, if they please–for example, removing negative personality traits like resentment, excessive fear, etc.

Martian Time-Slip, published in 1964, takes place on Mars in the late 1990s. The United Nations has begun colonizing the red planet, “reclaiming” desert to serve as farmland and establishing settlements along the great canals. Water is scarce, as are fine foods and luxury goods. Most people subsist on water rations and whatever meager crops they can raise.

Jack Bohlen is a repairman flying from job to job in his Yee Company helicopter. He’s much in demand on a planet where new equipment is hard to get and old equipment must be kept running as long as possible. He can fix just about anything, from industrial refrigeration systems to encrypted cassette recorders to the animatronic teachers at the local public school.

Published in 1969, Philip K. Dick’s Ubik takes place in a fictional future of 1992. The corporate world is plagued by spies from Ray Hollis’ psionic agency. The psionics have various psychic powers including telepathy and precognition. They infiltrate organizations to steal their valuable secrets.

Joe Chip is a tester for Runciter Associates, the world’s leading prudence organization. Prudence organizations find “inertials,” people whose psychic counter-talents can neutralize the talents of Hollis’ psionics. They’re in high demand by companies that have been infiltrated by psionics and are bleeding information.

The Three Stigmata of Palmer Eldritch opens in New York City in an unnamed year of the twenty-first century. Barney Mayerson, a pre-fash consultant for Perky Pat Layouts, drank too much the night before and slept with his new assistant, Rondinella “Roni” Fugate. Mayerson and Fugate are both precogs, blessed with a talent for seeing into the future.

Philip K. Dick’s The Man in the High Castle presents an alternate reality in which the Allies lost World War II and the Axis won. The book was written in, and takes place in, the early 1960’s. Unlike many of today’s dystopian alternate-history novels, which tend to be dark and somber, Dick’s story is darkly humorous.

Instead of focusing merely on how the victors oppress the vanquished, Dick transposes the absurdities and petty quarrels of twentieth century life onto an America colonized by Japan, a world in which two cultures, fundamentally at odds, must coexist without being able to fully understand each other.

Stanislaw Lem’s His Master’s Voice is science fiction of the highest order: a meditation on man’s place in the cosmos, an examination of the limits of our knowledge, and a scathing condemnation of how politics influences the practice of science. Originally published in 1967, this title, along with a number of Lem’s other works, was reissued in 2020 by MIT press.

The opening chapters provide a brief backstory. Australian scientists, granted access to the Palomar Observatory, spent two years studying neutrino emissions raining down from space. Nothing came of their work, and they left behind only the computer tapes containing recordings of the emissions.

The most disturbing thing about this book is that the vapid, false, and mind-numbing world that the media produces and the population so whole-heartedly consumes is so much like our own. The narrator points out more than once that the government didn’t take the initiative to ban books (and by extension, reflection and depth of thought and experience); the people themselves stopped wanting them.

This classic has good suspense and, as always from Levin, is well plotted. I won’t bother to summarize, since so many others already have, but it’s interesting to see a writer bring out the spooky side of sunshine and clean floors and fresh-smelling laundry.
