The scariest legends are about to come true! Molly Thompson has lots of questions. Questions like, is her Aunt Carol an undead fiend who drinks the blood of the living? Is she secretly lurking in the attic? And is Molly's friend Lowry a descendant of a long line of Kroglin werewolves? Serious young historian Molly suspects that the creepy legends about her tourist town of Howlfair are starting to come true.

They want Molly to help them find a hidden crypt that was never meant to be opened - and they won't take no for an answer...
