The Vatican has lost its most closely held secret--irrefutable proof of a woman Messiah named Sophia. Born in the Holy Land in 310 AD, Sophia was known for performing healing miracles. Her divinity threatened early Christian dogma and she was executed as a girl by Church authorities. In the present, Kate Sheridan visits Switzerland with her husband, where she expects to purchase the estate of a German art collector. But before Kate can complete the transaction, they are drawn into a thousand-year-old web of conspiracy and intrigue that begins and ends with the mystery of Sophia--and all the powerful forces who share the objective of protecting their patriarchies from a divinely feminine truth.
