The Holy Grail of Eris

Connie, who is the daughter of a Viscount whose only value is her honesty, and Scarlet Castiel, who was the most despised villain of the time and was executed ten years ago. The story that ought to have ended with Scarlet's death began anew when the two people who were never supposed to meet met at a night party. They only started dating because they were both interested in the same things, but they soon became real partners because they wanted to find out the truth about a huge conspiracy from the past that still has a bad hold on the present.
