To earn his Ghosthunting Diploma, Tom’s got to nab a deadly Twelfth Messenger. But while on the hunt in the haunted town of Bogpool, Tom stumbles into the mucked-up lair of a mud-loving minotaur who has an entire army of ghosts at his command. Suddenly there’s a lot more at stake than Tom’s graduation. This raging beast is dead-set on doomsday–and that’s no bull!
Horrifying things are happening at Gloomsburg Castle. To begin with, the creepy place is crawling with Tiny Biting Ghosts (or “TIBIGs,” in official ghosthunter code). And now it appears as if the murderous spirit of a brutal Baroness has taken hold of the land-lady, infecting her with a killer case of hic–hic–hiccups! Of course Hugo the Averagely Spooky Ghost is instantly smitten with Her Hideous Highness, only to find out that love stinks! And it smells something awful, too. Looks like the time has come for Tom to put an end to the “foul” play and concoct a plan that will dispel this decaying royal for good.
Can Tom and the team “dampen the spirit”–permanently!–of a fiery phantom, or are they about to get burned? Boy hero Tom, Hugo the Averagely Spooky Ghost, and famed ghoul hunter Hetty Hyssop have formed an agency dedicated to dealing with difficult apparitions. No spook can defeat them–until their too close encounter with a Gruesome Invincible Lightning Ghost. This superheated specter (or “GILIG,” in ghosthunter-speak) has taken over the penthouse suite of a beachfront hotel, where it’s passing its eternal vacation by turning guests into ghosts themselves! Maybe Hugo’s slime can douse the flaming phantom–or maybe the ghosthunters’ plan is doomed to go up in smoke. . . . Get scared silly!
Look out for ghost goo! Dripping sticky green slime wherever it goes, an “ASG” (that’s Averagely Spooky Ghost) is hiding out in Tom’s cellar. Why? Because it’s being haunted, too — by a much bigger, way badder Incredibly Revolting Ghost (“IRG,” for anyone new to ghouls). And the IRG is the kind of ghost that uses its head — as a ginormous bellowing bowling ball, gross! Good thing for Tom his grandma’s best friend just happens to be a world-famous ghosthunter…
