Years ago when he was young, before he came to Oseille and before the world started to change, Fiachra had another sister. Aoife was his twin and looking at her was as good at looking into a mirror. Except she was always more daring and, at four years old, she was still certain of her own immortality. She ranged further from their mother's house than he ever dared and she never wanted to hide when raiders or foxes came by.
Sometimes, Fiachra is still started awake by the sound of his sister's laughter ringing in his ears. Then he takes out the locket-a gift for Aoife's fourth birthday-and he renews his old vow to protect his family, and all those he loves, in her memory. Its been twenty-one years since she died, and Fiachra is the only one in the world who still remembers his sister or knows where she's buried, but he is determined she won't be lost.
