Jenny is a small story told in four short scenes about a girl who seems to belong to the sea rather than the land. She lives on the rocks, walks the beach at night, and sings as if trying to keep old sadness away, yet she never touches the water. The poem calls her the Sea's daughter, which suggests she is holding herself back from where she truly belongs.
Then, calmly, she walks in. The sea welcomes her, and her smile makes it feel like a reunion, as though the water were asking where she has been all this time. The last lines turn the story into a town legend: the Sea King's daughter was lost and is now found, and the waves no longer reach for the rocks because she isn't there.
The mood is gentle, wistful and a little eerie. It could be read as a fairy tale of homecoming, or as something sadder, since her walking into the sea might also hint at death. The poem leaves both readings open.
