In 1161 A.D., Merek gifts his cousin and lover Maerwynn a silver ring, adorned with strange symbols and a black stone. That same night, an unwelcome visitor to Maerwynn's chambers, forces her to throw the ring out the castle window and into the river below to try and save her and Merek's life. 800 years later, the ring appears once again in a small auction house in modern day New York City. Maerwynn, now Rachel, and her companion Lilith, want it at any price. They aren't the only ones.

The ring has secrets, but so do Rachel and Lilith. Can they still trust each other once their secrets unravel and they discover their connection to the ring and their part in a giant power struggle in Heaven?
