Fifteen-year-old Kira Hale maps "safe routes" to avoid crowds-until a brass compass and a blank quadrant labeled "Here Be You" send her into Northbridge's misty canals. With audio-savvy Ivy and photographer Miles, she builds a community Story Atlas of desire paths and a forgotten iron footbridge worth saving. A flood, a public hearing, and family pressures force Kira to speak for places-and for herself. A tender coming-of-age about anxiety, belonging, and charting who you are, revision by revision, one walked line at a time.
