Description

The most exciting road trip in history begins! In this action-packed, New York Times bestselling adventure, twelve-year-old twins Coke and Pepsi McDonald embark on a family vacation you'll have to read to believe.

Coke McDonald and his twin sister, Pepsi, think their family’s cross-country RV vacation is nothing to get excited about...until they’re chased off a cliff, locked in a burning school, and receive mysterious messages in codes and ciphers. From California to Wisconsin, it’s a race against time to find out who’s after Coke and Pep, who’s leaving the notes...and just what being a part of The Genius Files entails!

With the real-kid humor that has earned Dan Gutman millions of fans around the world, and featuring weird-but-true American tourist destinations, The Genius Files is a one-of-a-kind mix of geography and fun.

And don't miss the next leg of the journey in The Genius Files: Never Say Genius!


This secret mission will take them to the weirdest corners of America. Can two bickering twins outsmart the world’s most dangerous villains?
