The Lightning Thief is based on the idea that the Ancient Greek gods and goddesses are still alive and still ruling the earth, sea, and sky. Mount Olympus, the home of the gods, follows the heart of Western Civilization wherever it goes and is now located on the 600th floor of the Empire State Building in New York. Our narrator, Percy, discovers that he is very much a part of this tradition, and throughout the story he learns more and more about the customs of this tradition. At the heart of this story and of Percy's quest is a plot to destroy Greek gods and goddesses. Many are beginning to question the traditions and customs that have ruled for thousands of years. Some view tradition and customs as a means of manipulating a people, while others revere tradition and customs for the way they protect and celebrate humanity and civilization. We are left wondering whether change might be a good thing or an incredibly destructive thing.
