Spin is Robert Charles Wilson's Hugo Award-winning masterpiece―a stunning combination of a galactic "what if" and a small-scale, very human story. One night in October when he was ten years old, Tyler Dupree stood in his backyard and watched the stars go out. They all flared into brilliance at once, then disappeared, replaced by a flat, empty black barrier. He and his best friends, Jason and Diane Lawton, had seen what became known as the Big Blackout. It would shape their lives. The effect is worldwide. The sun is now a featureless disk―a heat source, rather than an astronomical object. The moon is gone, but tides remain. Not only have the world's artificial satellites fallen out of orbit, their recovered remains are pitted and aged, as though they'd been in space far longer than their known lifespans. As Tyler, Jason, and Diane grow up, a space probe reveals a bizarre truth: The barrier is artificial, generated by huge alien artifacts. Time is passing faster outside the barrier than inside―more than a hundred million years per year on Earth. At this rate, the death throes of the sun are only about forty years in our future. Jason, now a promising young scientist, devotes his life to working against this slow-moving apocalypse. Diane throws herself into hedonism, marrying a sinister cult leader who's forged a new religion out of the fears of the masses. Earth sends terraforming machines to Mars to let the onrush of time do its work, turning the planet green. Next they send humans… and immediately get back an emissary with thousands of years of stories to tell about the settling of Mars. Then Earth's probes reveal that an identical barrier has appeared around Mars. Jason, desperate, seeds near space with self-replicating machines that will scatter copies of themselves outward from the sun―and report back on what they find. Life on Earth is about to get much, much stranger.

Wildly praised by readers and critics alike, Robert Charles Wilson's Spin won science fiction's highest honor, the Hugo Award for Best Novel. Now, in Spin's direct sequel, Wilson takes us to the "world next door"—the planet engineered by the mysterious Hypotheticals to support human life, and connected to Earth by way of the Arch that towers hundreds of miles over the Indian Ocean. Humans are colonizing this new world—and, predictably, fiercely exploiting its resources, chiefly large deposits of oil in the western deserts of the continent of Equatoria. Lise Adams is a young woman attempting to uncover the mystery of her father's disappearance ten years earlier. Turk Findley is an ex-sailor and sometimes-drifter. They come together when an infall of cometary dust seeds the planet with tiny remnant Hypothetical machines. Soon, this seemingly hospitable world will become very alien indeed—as the nature of time is once again twisted, by entities unknown.

Vortex tells the story of Turk Findley, the protagonist introduced in Axis, who is transported ten thousand years into the future by the mysterious entities called "the Hypotheticals." In this future humanity exists on a chain of planets connected by Hypothetical gateways; but Earth itself is a dying world, effectively quarantined. Turk and his young friend Isaac Dvali are taken up by a community of fanatics who use them to enable a passage to the dying Earth, where they believe a prophecy of human/Hypothetical contact will be fulfilled. The prophecy is only partly true, however, and Turk must unravel the truth about the nature and purpose of the Hypotheticals before they carry him on a journey through warped time to the end of the universe itself.
