Vital Moysett has spent half his life burying the tragic mistakes and deadly secrets of his youth, but in an instant he learns that even being the most celebrated cathedral architect in 13th-century France and a favorite of Louis IX is not enough to protect him from his enemies' rage.
When his latest design suffers an inexplicable collapse, the terrified locals believe the devil himself pulled the daring vaults down. But Vital sees evil of a very human kind--and the threat of even greater destruction to come.
His frantic search to identify the next target turns into a maddening series of philosophical riddles and strangely personal attacks motivated by knowledge of his childhood that no one still alive could possibly have. With the help of his unusual wife and the famed encylopedist Vincent of Beauvais, he follows his tormentors to the glorious cathedral at Chartres, knowing he is stepping right into their trap.
