What this book is about
On the planet Arbre, cloistered scholar-monks called avout live in concents behind walls, studying ancient mathematical philosophy—allowed contact with secular society only every one, ten, one hundred, or one thousand years. When an alien vessel appears in orbit, Fraa Erasmas and his companions are called into the world to help with a crisis that will require everything they know. One of the most ambitious philosophical science fiction novels ever written.
