Ghosts

Readers will learn about the supernatural world of ghosts-deciding if the noise in the dead of night is the house settling, or something more. They will discover the realm that ghosts may haunt and learn about the people who search for ghosts for a living. A 'twilight quiz' will then ask readers if they are ready to search for ghosts themselves, or if they should worry about those noises they're hearing as they drift to sleep.
