Leo's latest job came on a gold-plated punch card. The client was "The Echo"—a legendary lost siren song, a vocal track so pure it could make angels weep and stock prices tank. It was supposedly locked in a decaying satellite, Lullaby-7 , on a decaying polar orbit.

He tried to pull the throttle. His hand wouldn't move. The frequency was a warm chain around his wrist. Just one more verse , he thought. Just the bridge .

"I got a story," he said, handing it over. "But I left the song in the sky."

"You got it?" she asked, her real voice thin and reedy.

Phaedra looked at him, then at the card. For a second, her image cleared. She looked old, tired, and impossibly sad. "Nobody ever leaves it," she said. "It leaves a piece of you up there."

By day, Leo was a burned-out audio engineer, buffing static out of corporate podcasts. But by night, he was the Midnight Skimmer, piloting his refurbished Cessna 310, The Frequency , across the ionosphere. His passengers weren't people. They were sounds.

Leo walked back to The Frequency . He didn't start the engine. He just sat in the cockpit, pulled on his cheap, noise-canceling travel headphones, and tuned to a mundane jazz station. It sounded like cardboard. It sounded like safety.
