A battered saxophone. Three unsettling letters. One impossible note at 2:11 AM.

When Hannah Turner brings home an old saxophone from a rummage sale, she expects dust and rust—not a midnight performance from an instrument no one is playing. The deeper she digs into the life of Gene Wright, the musician who once owned it, the stranger the clues become: lighting inconsistencies, structural vibrations, harmonics no one could explain.

Now the saxophone is waking up. And it isn't done with her.
