A guest in the house

Abby is settling into married life: making coffee, cooking for David and her stepdaughter Crystal, spending evenings curled up together in front of the TV. For a quiet woman without many friends, she's proud of the life she has built, and desperately wants to believe they will all be happy. But what really happened to Crystal's mother, the artist who no-one speaks of? What secrets does their strange house by the water harbour, and what of Abby's old dreams and fears, of Lady Grey, the Knight and the Dragons?
