" A beautiful, swirled brown and white shell like the one Ursula used to wear, but larger. A whelk, not a nautilus. Vareet picked it up in wonder, turning it over in her hands, admiring its gleam in the moonlight. On a whim she put it to her ear.
Her eyes widened.
In the depths of the shell, she could hear what must have been the echo of distant waves... and also the song of a mermaid. "
