Neal Stephenson sold Anathem to Ravi Mirchandani at Atlantic Books via Rachel Calder at the Sayle Literary Agency. The book is “based in a universe similar to but not our own, where mathematicians and philosophers are sheltered from an illiterate and unpredictable ‘saecular’ world, until the day they must leave their safe haven to save the entire world from destruction.” Expected publication date is September 2008.
