Anathem

Since childhood, Raz has lived behind the walls of a 3,400-year-old monastery, a sanctuary for scientists, philosophers, and mathematicians. There, he and his cohorts are sealed off from the illiterate, irrational, unpredictable saecular world, an endless landscape of casinos and megastores that is plagued by recurring cycles of booms and busts, dark ages and renaissances, world wars and climate change. Until the day that a higher power, driven by fear, decides it is only these cloistered scholars who have the abilities to avert an impending catastrophe. And, one by one, Raz and his friends, mentors, and teachers are summoned forth without warning into the unknown.
