The Genius Files is a rollicking new series about twin brother and sister Coke and Pepsi, who have been recruited as part of a group of highly intelligent kids chosen to help solve the problems of the world with a fresh, kid's perspective. This book has something for everyone. There is action and humor from the get-go, in addition to tons and tons of interesting bits of information that any fact-collecting kid will devour. As the family sets off on their RV trip, they hit every off-beat (real life) museum they can find, such as the Museum of Pez Memorabilia, on their way to see the world's largest ball of string. The book is peppered with illustrations, photos, and maps that give readers a visual appreciation of the cross-country journey. There is an age-appropriate description of the events of 9/11 at the Pentagon, which inspired the man who created the Genius organization. Coke and Pep are frequently in life-threatening situations, but manage to use their brains in creative ways to save themselves every time. Their over-the-top antics include driving their parents' RV to chase a suspect, and emptying the contents of the RV's septic tank on a bad guy's head. Several adults are also in perilous situations, but there is no blood and there are no deaths. The story ends with a cliffhanger that will leave readers eager for the next book.
