For a thousand years men have denied her existence--Pope Joan, the woman who disguised herself as a man and rose to rule Christianity for two years. Now this compelling novel animates the legend with a portrait of an unforgettable woman who struggles against restrictions her soul cannot accept. 

When her older brother dies in a Viking attack, the brilliant young Joan assumes his identity and enters a Benedictine monastery where, as Brother John Anglicus, she distinguishes herself as a scholar and healer. Eventually drawn to Rome, she soon becomes enmeshed in a dangerous mix of powerful passion and explosive politics that threatens her life even as it elevates her to the highest throne in the Western world.
