Walking with Superman: Day 239

When conditions are right at the Kelso Dune Field at the Mojave National Preserve in southeastern California, the sand itself begins to sing in a low, booming tone. Such singing sands exist in only a handful of places around the world, and while they typically sing solo, today the Kelso Dunes are playing backup. The Silver Banshee has come to California, hoping that the song of the dunes holds the key to restoring her humanity, and she's not about to let anyone stop the music, especially Superman! But has the Man of Steel come to apprehend her, or is the song she's singing written for a trio?
