Long before the days of Madman Jackson Muir, a witch named Isobel the Apostate made war upon her fellow sorcerers, the noble order of the Nightwing. Backed by an army of bloodthirsty demons, she became the most feared woman in all of Europe, even challenging King Henry VIII for the throne of England. Burned at the stake for her crimes, Isobel vowed to return and conquer the world...She kept her word! Now, she is back, and the only person who can prevent hell on earth is fourteen-year-old Devon March.
