Down at the bottom of the tall buildings of New York City, Magnolia Wu sits inside her parents' laundromat. She has pinned every lost sock from the laundromat onto a bulletin board in hopes that customers will return to retrieve them. But no one seems to have noticed. In fact, barely anyone has noticed Magnolia at all. What she doesn't know is that this is about to be her most exciting summer yet. When Iris, a new friend from California, arrives, they set off across the city to solve the mystery of each missing sock, asking questions in subways and delis and plant stores and pizzerias, meeting people and uncovering the unimaginable. With each new encounter, Magnolia learns that when you're bold enough to head into the unknown, things start falling into place.
