Booklist Review
In the fourth book of the Genius Files series, the McDonald family continues their cross-country road trip. Oblivious to danger, Mom insists on stopping at every weird tourist attraction and museum, while Dad just wants to drive his midlife crisis Ferrari. From the exploding RV at Tennessee's Graceland to the cliff-hanger ending in Roswell, New Mexico, twins Coke and Pepsi are intent on outwitting their murderous enemies and staying alive. As narrator, Gutman takes readers into his confidence and delivers suspense, hair-raising danger, and laughs, along with odd factoids about Arkansas, Oklahoma, Texas, and New Mexico. Series fans will be lining up for book five.--Phelan, Carolyn Copyright 2014 Booklist
