Talia Vasic (nee Lydenses) is Adam Vasic's mother, and the wife of Robert Vasic. Talia is first mentioned in Stolen by the scientists at the compound who found it fascinating that she bore the son of a demon, and then later married an unrelated half-demon. As it turns out, Talia met Robert while searching for answers about Adam's "condition," (as Robert was the professer of demonology at a university) and the two fell in love. The short story Demonology was focused on her and her discovering the supernatural world.
