From the Publisher:
It’s the middle of the night. Screams and hideous howls rouse a slumbering schoolboy from his dormitory bed.
Rushing outside, Basil Hastings watches in horror as terrified classmates are snatched up and carried off by large, lurching, loathsome figures.
Bog zombies!
Before he can escape, Basil is scooped up in a clammy, smelly embrace, and hauled away to an unknown fate.
Into this cauldron of anarchy and danger, Johnny Graphic arrives to shoot pictures for the ZENITH CLARION. But what starts as a newspaper assignment turns into a desperate mission to rescue hundreds of abducted kids. And Johnny is pretty sure he knows who the evil genius is behind all this mayhem—Percy Rathbone, the most dangerous ghost on the planet.
Continuing in the rip-roaring style of the first Johnny Graphic adventure, this second installment in the trilogy is full of thrills and chills, as Johnny and his friends—living and dead—battle to defeat the attack of the zombies.
