[Read by Michael Goldstrom] The most dangerous road trip in history continues for thirteen-year-old twins Coke and Pepsi McDonald. Just when they think they are safe, the McDonald twins are chased by an evil Elvis impersonator, trapped in a pool of flesh-eating soda pop, nearly pulverized in a giant shredder, and crushed in a turbo-charged carnival ride. Worst of all, no one believes them! -- Will they make it out alive? Will they ever find out who's really after them? All bets are off in this explosive third book in the 'Genius Files' series.
