Scorpio Rose was published by Eclipse in 1983.
Rosa, was a beautiful gypsy girl. One day, a stranger came to her encampment and Rosa danced for him. Afterward, they stole away to a secluded cliff. It was there that Rosa found out the stranger was no human, but harbored a demon from the pit. He took Rosa, harshly, violating her body and her soul. He also blessed—or cursed—her with eternal life.
Three hundred years later, Rosa lives in Paris where she makes her living as a seer. She has learned the ways of magic, but little did she suspect that she would be using them to save her life from the same demon that changed her so many years ago.
