Hannah is hard at work writing a scary story for school when she suddenly finds herself listening to spooky stories in a firelit cabin in the Appalachian Mountains. As everyone prepares for the upcoming autumn festival, Hannah must help Annie, a girl her own age, who suspects that her brother Rufus has been kidnapped. Piecing together clues sent by the angels, Hannah and Annie brave all kinds of dangers--including a stormy encounter on a precarious bridge--to bring Rufus safely home.
This is one of the book series I remember constantly checking out at the library as a kid, along with Nancy Drew. Reading it now brought more nostalgia than I expected. This series is somewhat educational, inserting little facts throughout the story of the place it takes place in. I even learned a few things I didn't know. Overall, I think it's great for kids and wish I could find them a little easier. They never got popular and are out of print unfortunately.
