The last kids on earth and the doomsday race

I'm Jack Sullivan, and this is why you should vote for me to be mayor of Mallusc City: I've pretty much mastered the art of zombie-control, taken down massive monsters, and survived the most epic road trip ever. Now I'm ready for anything! But it turns out travelling on the back of an enormous centipede monster means less sightseeing than planned, and more foe-fighting superhero-ness than ever before... But the Destructor of Worlds has nothing on me, my awesome gang of monster-fighting friends and my radical zombie squad. Whatever it takes, we're gonna win the Doomsday Race - and save the world!
