The Lion the Witch and the Wardrobe 85 million

Starting a line of primarily British author domination for the remaining places on our list, C.S. Lewis and his fantasy novel The Lion, the Witch, and the Wardrobe come in at #8 with 85 million copies sold. Present in many a high school English class, the novel follows the story of four English children completing their destiny in the land of talking animals and mythical beings. Though the book is only one the first in a sevennovel series, it is by far the bestselling.
