The ghostkeeper's journal & field guide

"Welcome to SPRUNG, the Society for the Pursuit of the Reputedly Undead, Namely Ghosts! Agamemnon White--SPRUNG Ghostkeeper and child prodigy--has disappeared. All that remains of him is his journal, which you now hold in your hands. As head Ghostkeeper for the Western region, Ag was collecting the most powerful ecto-energy types known to man . . . in this very book. Your task? To join SPRUNG, read Ag's journal, use the Ghost-o-Matic app to retrace his footsteps, and help rescue him. But beware . . . the moment you open this book, you will release the ghosts Ag trapped inside. It's up to you to recapture them and solve the mystery of his disappearance . . . without disappearing yourself"--OCLC.
