Billy Dean is a secret child, growing up in the dark heart of Blinkbonny. He has a beautiful young mother and a father who arrives at night carrying the scent of incense and cigarettes. His world is just a bed, some pictures of the holy island and a single locked door, but his father fills his dreams with mysterious tales and dreadful warnings. When his father disappears, Billy's mum brings him out into the world, and he learns the dreadful truth of what happened in Blinkbonny on the day he was born. Gradually he finds he has the gift of helping to rebuild what has been broken. But there is one figure who is beyond healing, who comes looking for Billy himself and is determined on a kind of reckoning.
