In the darkness of a underground cave system, blind creatures hunt by sound. Then there is light, there are voices, and they feed... Swarming from their prison, the creatures thrive and destroy. To scream, even 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 many 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, to find a remote haven where they can sit out the plague. But will it ever end? And what kind of world will be left?
