In the seaside town of Carron Bay, an old public library opens its doors only one day each year, without announcement or explanation. When Elias Moore arrives on that single day by accident, he discovers that the library does not lend books—it listens. Each chapter reveals how the library gathers unfinished thoughts, unspoken decisions, and quiet truths from those who enter. As Elias returns year after year, he learns that some places exist not to provide answers, but to hold questions safely until people are ready to carry them themselves.
