Neal Town Stephenson (born October 31, 1959) is an American writer, known for his speculative fiction works, which have been variously categorized science fiction, historical fiction, maximalism, cyberpunk, and postcyberpunk. Stephenson explores areas such as mathematics, cryptography, philosophy, currency, and the history of science. He also writes non-fiction articles about technology in publications such as Wired Magazine, and has worked part-time as an advisor for Blue Origin, a company (funded by Jeff Bezos) developing a manned sub-orbital launch system.

Born in Fort Meade, Maryland (home of the NSA and the National Cryptologic Museum) Stephenson came from a family comprising engineers and hard scientists he dubs "propeller heads". His father is a professor of electrical engineering whose father was a physics professor; his mother worked in a biochemistry laboratory, while her father was a biochemistry professor. Stephenson's family moved to Champaign-Urbana, Illinois in 1960 and then to Ames, Iowa in 1966 where he graduated from Ames High School in 1977. Stephenson furthered his studies at Boston University. He first specialized in physics, then switched to geography after he found that it would allow him to spend more time on the university mainframe. He graduated in 1981 with a B.A. in Geography and a minor in physics. Since 1984, Stephenson has lived mostly in the Pacific Northwest and currently resides in Seattle with his family.

Neal Stephenson is the author of the three-volume historical epic "The Baroque Cycle" (Quicksilver, The Confusion, and The System of the World) and the novels Cryptonomicon, The Diamond Age, Snow Crash, and Zodiac. He lives in Seattle, Washington.

From the #1 New York Times bestselling author of Anathem, Reamde, and Cryptonomicon comes an exciting and thought-provoking science fiction epic—a grand story of annihilation and survival spanning five thousand years.

What would happen if the world were ending?

A catastrophic event renders the earth a ticking time bomb. In a feverish race against the inevitable, nations around the globe band together to devise an ambitious plan to ensure the survival of humanity far beyond our atmosphere, in outer space.

But the complexities and unpredictability of human nature coupled with unforeseen challenges and dangers threaten the intrepid pioneers, until only a handful of survivors remain . . .

Five thousand years later, their progeny—seven distinct races now three billion strong—embark on yet another audacious journey into the unknown . . . to an alien world utterly transformed by cataclysm and time: Earth.

A writer of dazzling genius and imaginative vision, Neal Stephenson combines science, philosophy, technology, psychology, and literature in a magnificent work of speculative fiction that offers a portrait of a future that is both extraordinary and eerily recognizable. As he did in Anathem, Cryptonomicon, the Baroque Cycle, and Reamde, Stephenson explores some of our biggest ideas and perplexing challenges in a breathtaking saga that is daring, engrossing, and altogether brilliant.
