Killing sound

Jodie is cursed with a terrible gift. She just doesn't know it yet. When she stumbles across one of her dead father's old papers on sound waves in the attic, it sets her on a terrifying journey to find out more, leading her across the streets of London to the dark, untrodden tunnels of the Underground, where she is forced to face the truth. Her worst nightmare is about to become real. Worse, she can hear it coming.
