New Stephenson

As per this news. The novel is titled Anathem, and the blurb follows:

Since childhood, Raz has lived behind the walls of a 3,400-year-old monastery, a sanctuary for scientists, philosophers, and mathematicians — sealed off from the illiterate, irrational, unpredictable “saecular” world that is plagued by recurring cycles of booms and busts, world wars and climate change. Until the day that a higher power, driven by fear, decides that only these cloistered scholars have the abilities to avert an impending catastrophe. And, one by one, Raz and his cohorts are summoned forth without warning into the Unknown.
