All Penny Panic wants is for her favorite SPIRIT-sponsored events to continue. What else is there to do in the afterlife but attend Dinner with the Dead potlucks, Resting in Peace Yoga classes, and Kick-the-Bucket Book Club meetings? But keeping SPIRIT alive–er, keeping it going–will require every ghost's help. Can Penny overcome her panic to scare humans and save SPIRIT?

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.
