Haley and Dodger don't have much in common. Haley lives in Greenhaven, Connecticut; Dodger lives in Port Salmon, Washington. Haley has a family who loves and supports her; Dodger can't seem to ever get his dad's approval. Haley is well adjusted and passionate; Dodger hears strange voices in his head. But they both want something: a new map, a path away from home--or, perhaps, a path toward it.

Of course, this was all before they heard about the missing people, the untraceable radio signals, the unexplained phenomena. Before they both became the first recipients of a summer research grant from a certain mysterious foundation. Before they discovered that their fledgling theories about extraterrestrial life were all too accurate.

Now Haley and Dodger are the only ones who can figure out what is happening in towns across America, who can give voice to the people whispering "alien abduction." At the very least, they're both going to have the most eventful summer vacations of anyone they know.
