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.

From handshakes and toasts to chant and genuflection, ritual pervades our social interactions and religious practices. Still, few of us could identify all of our daily and festal ritual behaviors, much less explain them to an outsider. Similarly, because of the variety of activities that qualify as ritual and their many contradictory yet, in many ways, equally legitimate interpretations, ritual seems to elude any systematic historical and comparative scrutiny. In this book, Catherine Bell offers a practical introduction to ritual practice and its study; she surveys the most influential theories of religion and ritual, the major categories of ritual activity, and the key debates that have shaped our understanding of ritualism. Bell refuses to nail down ritual with any one definition or understanding. Instead, her purpose is to reveal how definitions emerge and evolve and to help us become more familiar with the interplay of tradition, exigency, and self-expression that goes into constructing this complex social medium.
