Ever since a car accident left Tillie Green with lasting painful injuries, she's hidden behind her camera. She watches her family and classmates through the lens, tracking down misplaced items and spotting the small details that tell a much bigger story than people usually see. But she isn't prepared for class clown Jake Hausmann's request: to find his father. In a matter of days, Tillie goes from silent observer to one half of a detective duo, searching for clues to the mystery of Jake's dad's disappearance. When the truth isn't what Jake wants it to be, and the photographs start exposing people's secrets, Tillie has to decide what-and who-is truly important to her.-- Publisher's description.
