Two kids from opposite sides of the country find themselves on a road trip to save the world from an impending alien attack - and bolster their middle-school transcripts in the process. First came the missing people, missing time events, and untraceable radio signals. Then came Juliette, Arizona, a town that simply disappeared from existence. Suffice it to say, something strange is going on. Enter Haley and Dodger, two kids from opposite sides of the country who both think they can prove that these unexplained phenomena have a very real cause: aliens, and they are about to discover that their fledgling theories about extraterrestrial life are one-hundred-percent accurate. Having each been awarded a Fellowship for Alien Detection (a grant from a mysterious foundation dedicated to proving aliens have visited earth), Haley and Dodger and their families each set off on a cross-country road trip over summer vacation to figure out what is happening in towns across America. They soon realize that the answers to many of their questions lie in the vanished town of Juliette, AZ, but someone, or something, is doing everything in its power to ensure they never reach it. If Haley and Dodger don't act quickly, more people may go missing, and the world as we know it may change for the worse.
