Every day, more and more people fleeing war in the north show up at Kyung Tak and her family's house on the southeastern shore of Korea. With nowhere else to go, the Taks' home is these migrants' last chance of refuge "before falling into the sea," and the household quickly becomes crowded, hot, and noisy. Then war sirens cry out over Kyung's city too, and her family and their guests take shelter underground. When the sirens stop, Kyung is upset--she wishes everything could go back to the way it was before: before the sirens, before strangers started coming into their home. But after an important talk with her parents, her new friend Sunhee, and Sunhee's father, Kyung realizes something important: We're stronger when we have each other, and the kindness we show one another in the darkest of times is a gift we'll never regret.
