A man who had no voice. A woman who helped him find it. Rob and Anna have only just met Owen and Kim. Now they've chartered their handsome old boat to take them to a far off island in the Caribbean.
With just the four of them on board, Rob dreams of lazy afternoons snorkelling. Anna looks forward to the silence and solitude of the sea.
But why does Owen suffer acute insomnia and seem so secretive about his past? Why does Kim keep a knife zipped into her money-belt? Anna, a speech therapist, can usually get people to tell her the truth... but does she want to this time?
