The Silence By Tim Lebbon. Now, it is her family's only chance of survival. In the darkness of a vast cave system, cut off from the world for millennia, blind creatures hunt by sound. But will it ever end? And what kind of world will be left. Swarming from their prison, they multiply and thrive. To leave their home, to shun others, to find a remote haven where they can sit out the plague. To scream, even to whisper, is to summon death. Deaf for many years, Ally knows how to live in silence. Then there is light, there are voices, and they feed.
