A Wan watches over a boat that searches for people. With the Remembrance Compass in her hands, she can follow the obsessions that bind people's hearts and help them find the people and things they cannot let go of. Yet after spending a thousand years searching for others, she still cannot find her own missing master, Wen Jing. Now, with only a few spaces left to complete the thirteen-slot Remembrance Compass, A Wan travels from place to place, helping others untangle their heart's knots while gradually drawing closer to the answer she has awaited for a thousand years. Only at the very end does she discover that perhaps, throughout these thousand years, she was never searching for someone who had long since departed—because that person may never have truly left her.
