Setting

The Lightning Thief is set in the early 21st century, offering a modern take on ancient Greek mythology. The story primarily unfolds across the United States, with key locations including New York City, Long Island, and Los Angeles. This contemporary setting allows for a unique juxtaposition of mythological elements with familiar modern landscapes.

Camp Half-Blood, located on Long Island, serves as a crucial backdrop for much of the novel. This secluded training ground for demigods provides a safe haven where Percy and his fellow half-bloods can hone their skills and learn about their divine heritage. The camp's magical boundaries and ancient Greek-inspired architecture create a stark contrast to the bustling outside world.

As Percy's quest unfolds, the narrative takes readers on a journey across America. From the concrete jungle of Manhattan to the scorching deserts of the Southwest, and finally to the glittering lights of Los Angeles, the diverse settings reflect the vastness and variety of the American landscape.
