Fraa Erasmus is a young avout living in the Concent of Saunt Edhar, a sanctuary for mathematicians, scientists, and philosophers, protected from the corrupting influences of the “Saecular” world by ancient stone, honored traditions, and complex rituals.Over the centuries, cities, and governments have risen and fallen beyond the concent’s walls. Three times during history’s darkest epochs, bloody violence born of superstition and ignorance has invaded and devastated the cloistered mathic community. Yet always the avout have managed to adapt in the wake of catastrophe, becoming out of necessity more austere and less dependent on technology and material things. Erasmus, however, has no fear of the outside – the Extramuros – for the last of the terrible times was long, long ago.

Now, in celebration of the week-long, once-in-a-decade rite of Apert, the fras and suurs prepare to venture outside the concent’s gates – opening them wide at the same time to welcome the curious “extras” in.

During his first Apert as a fra, Erasmus eagerly anticipates reconnecting with the landmarks and family he hasn’t seen since he was “collected”. But before the week is out, both the existence he abandoned and the one he embraced will stand poised on the perilous brink of cataclysmic change.

Powerful unforeseen forces threaten the peaceful stability of mathic life and the established ennui of the Extramuros – a threat that only an unsteady alliance of Saecular and avout can oppose – as, one by one, Raz’s colleagues, teachers, and friends are all called forth from the safety of the concent in hopes of warding off global disaster.

Suddenly burdened with a worlds-shattering responsibility, Erasmus finds himself a major player in a drama that will determine the future of everything – as he sets out on an extraordinary odyssey that will carry him to the most dangerous, inhospitable corners of an unfamiliar planet…and far beyond.

In 1972, Richard Forthrast, the black sheep of an Iowa farming clan, fled to the mountains of British Columbia to avoid the draft. A skilled hunting guide, he eventually amassed a fortune by smuggling marijuana across the border between Canada and Idaho. As the years passed, Richard went straight and returned to the States after the U.S. government granted amnesty to draft dodgers. He parlayed his wealth into an empire and developed a remote resort in which he lives. He also created T’Rain, a multibillion-dollar, massively multiplayer online role-playing game with millions of fans around the world.

But T’Rain’s success has also made it a target. Hackers have struck gold by unleashing REAMDE, a virus that encrypts all of a player’s electronic files and holds them for ransom. They have also unwittingly triggered a deadly war beyond the boundaries of the game’s virtual universe – and Richard is at ground zero.

Racing around the globe from the Pacific Northwest to China to the wilds of northern Idaho and points in between, Reamde is a swift-paced thriller that traverses worlds virtual and real. Filled with unexpected twists and turns in which unforgettable villains and unlikely heroes face off in a battle for survival, it is a brilliant refraction of the 21st century, from the global war on terror to social media, computer hackers to mobsters, entrepreneurs to religious fundamentalists. Above all, Reamde is an enthralling human story – an entertaining and epic pause-resister from the extraordinary Neal Stephenson.
