Chess (12), Emma (10), and Finn (8) come home from school one day to find their mother in despair over a news story about a bizarre kidnapping—bizarre because the three children who were taken share the names, ages, and birthdays of the Greystone kids. Then Mrs. Greystone is called suddenly out of town, leaving her kids in the care of a stranger, with nothing but questions and a coded letter.
