Erika and the Skeleton Staff

Erika had heard strange stories about snow days at school. Days when school wasn't quite closed, lessons were abandoned, and teachers couldn't get into school. But there was something scary in their place...a Skeleton Staff!
When snow is forecast, Erika's imaginative mind runs riot. The stories of the skeleton staff can't possibly be true, can they? But when Erika and her friends discover a skeleton in one of the classrooms, her worst fears seem to be coming true.
Are skeletons really about to take over the school? And are they friend or foe?
This is going to be a school day like no other. One that Erika and her friends will never forget.
