The Game (Jones novel)  The Game is a children's fantasy novel written by Diana Wynne Jones. It explores a young girl's life and her relation to the "Mythosphere." This book pulls heavily from Greek and even some Russian mythology. Hayley’s parents disappeared when she was a baby. Since then, she has been raised and homeschooled by her grandparents. Grandad is overworked and travels a lot; Grandma is much too strict and never lets her meet any children her own age. When Hayley does something wrong—she is not quite sure what—they pack her off to her aunts in Ireland. To Hayley’s shock, her family is much bigger than she thought; to her delight, the children all play what they call “the game,” where they visit a place called “the mythosphere.” And while she plays the game, Hayley learns more about her own place in the world than she had ever expected. Hayley encounters various mythological figures during the course of her adventures in the mythosphere, including Actaeon and Baba Yaga.
