The Willow Witch — Howard Hopkins

When Allie "Alliecat" Carpenter sees the New Salem Witch flying across the face of the full moon she knows the trouble is just beginning. Somebody has helped the old hag escape her grave and legend has it she must kidnap seven children in seven days to become immortal, or perish forever. Soon, the children of New Salem begin disappearing and Allie knows the old legend is coming true. Together with a band of misfit ghost hunters who call themselves the Nightmare Club, she decides to track down the old witch and put her in her grave once and for all-if the witch doesn't get her first!
