Winner of the 1961 Hugo Award for Best Novel and widely considered one of the most accomplished, powerful, and enduring classics of modern speculative fiction, Walter M. Miller’s A Canticle for Leibowitz is a true landmark of 20th-century literature—a chilling and still-provocative look at a postapocalyptic future.

TWO HOSPITAL BEDS in a Stanford University lab. Two still figures, attached by bundles of cables to the experimental QARMA supercomputer. Analise and Wolfe are true scientific pioneers, the first humans to ever leave the shells of their physical bodies to explore an entirely new virtual universe beyond time and space. But their creation, the most vivid VR metaverse ever envisioned, has come under attack.

There has always been a darkness to Ilmar, but never more so than now. The city chafes under the heavy hand of the Palleseen occupation, the choke-hold of its criminal underworld, the boot of its factory owners, the weight of its wretched poor and the burden of its ancient curse. What will be the spark that lights the conflagration? Despite the city's refugees, wanderers, murderers, madmen, fanatics and thieves, the catalyst, as always, will be the Anchorwood–that dark grove of trees, that primeval remnant, that portal, when the moon is full, to strange and distant shores.

Breakfast of Champions (1973) provides frantic, scattershot satire and a collage of Vonnegut's obsessions. His recurring cast of characters and American landscape was perhaps the most controversial of his canon; it was felt by many at the time to be a disappointing successor to Slaughterhouse-Five, which had made Vonnegut's literary reputation.

In On the Genealogy of Morals, subtitled "A Polemic", Nietzsche furthers his pursuit of a clarity that is less tainted by imposed prejudices. He looks at the way attitudes towards 'morality' evolved and the way congenital ideas of morality were heavily colored by the Judaic and Christian traditions.

Imajica is an epic beyond compare: vast in conception, obsessively detailed in execution, and apocalyptic in its resolution. At its heart lies the sensualist and master art forger Gentle, whose life unravels when he encounters Judith Odell, whose power to influence the destinies of men is vaster than she knows, and Pie "oh" pah, an alien assassin who comes from a hidden dimension.

In what is considered one of Heinlein's most hair-raising, thought-provoking, and outrageous adventures, the master of modern science fiction tells the strange story of an even stranger world. It is 21st-century Luna, a harsh penal colony where a revolt is plotted between a bashful computer and a ragtag collection of maverick humans, a revolt that goes beautifully until the inevitable happens. But that's the problem with the inevitable: it always happens.

Our universe is ruled by physics, and faster-than-light travel is not possible - until the discovery of The Flow, an extradimensional field we can access at certain points in space-time that transports us to other worlds, around other stars. Humanity flows away from Earth, into space, and in time forgets our home world and creates a new empire, the Interdependency, whose ethos requires that no one human outpost can survive without the others. It's a hedge against interstellar war - and a system of control for the rulers of the empire.

In the 20th century Earth sent probes, transmissions, and welcoming messages to the stars. Unfortunately, someone noticed. The Galactics arrived with their battle fleet in 2052. Rather than being exterminated under a barrage of hell-burners, Earth joined their vast Empire. Swearing allegiance to our distant alien overlords wasn't the only requirement for survival. We also had to have something of value to trade, something that neighboring planets would pay their hard-earned credits to buy. As most of the local worlds were too civilized to have a proper army, the only valuable service Earth could provide came in the form of soldiers....
