A Touch of Darkness

Persephone, a young goddess, longs to experience the life of mortals. With her mother's magic, she takes on the guise of a mortal girl, graduates from college, and lands her dream job as a journalist. Her friend Lexa suggests celebrating her success at an elite club owned by Hades, the God of the Dead and ruler of the Underworld.
At the club, Persephone meets a mysterious stranger and asks him to teach her how to play cards. The stranger turns out to be Hades, and after losing to him, the goddess makes a fateful contract. Persephone has only six months to fulfill the terms of the agreement. If she fails, she will be forever bound to the gloomy realm of shadows.
