Deadstock, the world’s greatest zombie rock festival, is coming to Scream Street! Too bad Sir Otto Sneer is not in the mood for dancing—and when he banishes the concert’s headliners, the fleshmetal band Brain Drain, to the evil Underlands, he causes a riot. Now if Luke and his pals want to restore peace to the neighborhood (and find the fourth relic they seek), they have no choice but to follow the band . . . into the darkest depths of the earth.
