He can see sound. She (his deaf little sister Mina) can weaponize silence. Together with their K-9, they're the Echo Squad.
When 12-year-old Leo Park's sister Mina invents glasses that make sound visible, Leo thinks they'll get grounded for life. He's half right.
Now they can see three-day-old whispers, invisible crime scenes-and a villain no one else can detect. The Conductor uses infrasound: sound waves so low no human can hear them, but powerful enough to shatter jade, control minds, and collapse buildings.
His next target? A concert hall with 3,000 people inside. His instrument? A frequency that turns human ribs into tuning forks.
Leo, Mina, and their retired German shepherd Rusty have one night, one broken pair of glasses, and one theory about a humming night guard named Carlos. If they're wrong, the whole city hits a deadly note.
