Among the ghosts

The New Newbridge Academy has a strange, storied history and a gothic atmosphere, and since Noh’s aunt is a teacher there, it’s where Noh will be spending the summer while her father travels for work. Noh, slightly eccentric herself, enjoys exploring the campus, but things get spooky when she meets several other children near an old burned-out dormitory. There shouldn’t be students around in the summer, right? But these kids turn out to be ghosts, and they need Noh’s help. She is the only “realie” who can see them—and, now that the ghosts have started to disappear, the only one who can save them.
