The Book of Hidden Wonders

"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 clues leading to a precious prize. But as time passes, Romilly's father becomes increasingly suspicious of the outside world until, before her eyes, he begins to disappear altogether. With no-one else to help, Romilly turns to the secrets her father has hidden in his illustrated books - realising that his treasure hunt doesn't lead to gold, but to something far more precious... the truth."--Publisher's description.
