After the country rezombifies, Zack and the Zombie Chasers head out in search of a new antidote.

"The living dead are back and they mean business. After narrowly escaping a rezombified New York City, Zack Clarke and his team of Zombie Chasers Rice, Zoe, Ozzie, and Madison are on the hunt for a new and lasting antidote. Yet with the country fast becoming a horde of slack-jawed flesh eaters, the Zombie Chasers have nowhere else to turn . . . or do they? Their only hope of stopping the virus is to find Madison's twinlike cousin Olivia, but first they'll have to plow through abominable snow zombies on the Niagara River, then slime-drooling thrill seekers at the biggest and best amusement park in the country. And between rotting fairy-tale princesses and half-dead vacationers, it's not just the Tilt-a-Whirl that will make them woozy. Can the Zombie Chasers end this carnival of frights before it's too late?"--From publisher.
