Romilly lives in a ramshackle house with her eccentric artist father and her cat, Monty. She knows little about her past – but she knows that she is loved. When her father finds fame with a series of children’s books starring her as the main character, everything changes: exotic foods appear on the table, her father appears on TV, and strangers appear at their door, convinced the books contain a treasure hunt leading to a glittering prize. But as time passes, Romilly’s father becomes increasingly suspicious of everything around him, until, before her eyes, he begins to disappear altogether.
