For twelve years, Bella Bathurst's life was ruled by her deafness. She missed the punchlines and the jokes, avoided busy restaurants and raucous parties, grew her hair long to cover hearing aids, and retreated into herself. But then, twelve years later, pioneering surgery on her ears gave her the chance to hear again.

Sound is the extraordinary story of Bella's journey into deafness and back to hearing. Mixing memoir with interviews with soldiers, sign language experts, musicians and mental health workers, Bella explores what deafness teaches us about listening and silence, and what the deaf know that the hearing don't.

If sight gives us the world, then hearing - or our ability to listen - gives us each other.
