«The Silence» by Tim Lebbon

In the darkness of an underground cave, blind creatures hunt by sound. Then there is light, voices, and they feed… Swarming from their prison, the creatures thrive; to whisper is to summon death. As the hordes lay waste to Europe, a girl watches to see if they will cross the sea. Deaf for years, she knows how to live in silence; now, it is her family's only chance of survival. To leave their home, to shun others. But what kind of world will be left?
