Thirteen-year-old Jonah is adopted and his family has always made him feel loved and welcome. Out of the blue, he receives a mysterious letter that says only, "You are one of the missing." What does that mean? Even stranger, Jonah's friend Chip receives the same letter and he didn't even know he was adopted. The letters launch the boys into a mystery about their true identities that will lead them into stranger and stranger events. This is the first in a series that promises to be exciting and suspenseful.
