Romilly Kemp has an idyllic childhood, roaming the wilderness that surrounds her father's ramshackle farmhouse. But when he makes her the star of his beautifully illustrated books, her carefree if somewhat lonely existence is threatened.

The books are thought to hold clues to an elaborate treasure hunt, and strangers turn up at their door, anxious to get a glimpse of the 'Kemp Treasure Girl'. But when her father falls ill, leaving Romilly more isolated and alone than ever, she begins to delve deeper into the books - and her past. As she makes sense of the clues he has hidden, she finds a truth that is far darker and more devastating than any treasure hunt has a right to be.

For not everything that is hidden is gold.
