Ever since Tillie Green's car accident left her with a severe limp, she's kept herself hidden behind her camera. Through the lens, she watches her family and classmates, spotting the small details and secret glances that tell a much bigger story than what people usually see. Students call her "Lost and Found," because her camera knows when you last had your headphones. Tillie is good at finding things, but she isn't prepared for Jake's request: to find his father. In a matter of days, Tillie goes from silent observer to one half of a detective duo, searching the college-town community for clues to explain Jake's dad's disappearance. When the truth isn't what Jake wants it to be, and taking photographs starts exposing people's secrets, Tillie has to decide what (and who) is truly important to her.
