Errik has been a prisoner--and alone--for a long, long time. He lives for the moment each day when the window of his dungeon cell shines a bit of light onto his bearded face.But everything changes when he gets a new neighbor--a young girl with a voice as beautiful as the springrise. They both know the rules: No singing. No speaking. Voices are dangerous. But they can't help themselves. And soon enough, Errik begins to remember himself, why he's here in this dark place, and why his captors will stop at nothing to ensure his silence.
