Johnny Graphic and the Ghost of Doom - Johnny Graphic Adventures, #3

When a guy's about to get sacrificed to the volcano god, he might have some second thoughts about the choices he made that landed him in this pickle. But Johnny Graphic knows he couldn't have done it any other way. Because these mountainous, frozen wilds are where his parents went missing. And being here is his only chance to find them. That is, if he can manage to stay alive. It's the final chapter of Johnny Graphic's great ghost adventure.
And he and his sidekick Nina Bain have their work cut out for them. Not only must they survive human-sacrificing tribesmen, they have to fight off murderous ghost warriors. Face down giant ice wolves. Stay alive when a massive volcano erupts. Stop a war before it starts. Help ghosts to really, truly, properly die. Defeat the most dangerous ghost of all. And, on top of everything, save the entire planet from doom. It's a heckuva lot for a twelve-year-old news photographer to handle.
