He turned the crank handles, hoping the thing wouldn’t explode in his face. A few clear tones rang out-metallic yet warm. Leo manipulated the levers and gears. He recognized the song that sprang forth-the same wistful melody Calypso sang for him on Ogygia about homesickness and longing. But through the strings of the brass cone, the tune sounded even sadder, like a machine with a broken heart-the way Festus might sound if he could sing.
Leo forgot Apollo was there. He played the song all the way through. When he was done, his eyes stung. He could almost smell the fresh-baked bread from Calypso’s kitchen. He could taste the only kiss she’d ever given him.
