Twelve-year-old Jonah has always known that he was adopted, and he has never thought it was a big deal. Then he and a neighbor/friend, Chip, who finds out he is also adopted, begin receiving mysterious letters, saying things such as "You are one of the missing" and "Beware! They're coming back to get you". Jonah, Chip, and Jonah's younger sister, Katherine, are plunged into a mystery that involves the FBI, a vast smuggling operation, an airplane that appeared out of nowhere—and people who seem to disappear and reappear at will...
