Freddie McFright is eager to join the world's most elite scarers. After all, his grandfather was a founding member of SPIRIT and a legend among menaces. To prove himself, Freddie must haunt a family suffering from a serious case of SAD–Severe Apparition Denial. Can he scare them out of their un-boo-lieving ways?

The Society of Paranormal, Invisible, and Restless Imps and Terrors has a problem: due to so-called "science," the living are believing in ghosts less and less. To boost morale, SPIRIT is opening its doors to new members for the first time in centuries. But only the spookiest recruits will get to join the undead's most esteemed organization.
