Gracie O'Ghoul loves to help out her parents on their farm–but all her attempts at helping end in huge messes! Her parents decide that helping SPIRIT is just what Gracie needs to keep her busy. So, they send her to the local elementary school to scare her fellow students and earn her place in SPIRIT. Knowing it's her duty to disturb, Gracie will give it her bloodcurdling best. But what should a ghost do if she'd rather make friends?

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.
