Percy Jackson has ADHD, dyslexia, and a taste for trouble, so he's stuck going to a private school in upstate New York for hard-to-handle kids. If he doesn't get his life into shape, this could be the sixth school he's expelled from.
Then one day, Percy's world is turned upside down. His math teacher turns into a terrifying monster who tries to kill him, he finds out his best friend is half human and half goat, and he discovers the truth behind the father he never knew: his father is the Greek god Poseidon.
Now Percy is on his way to yet another school, a training camp for half-bloods on Long Island, where he finds himself at the center of a fierce battle between Poseidon, Zeus, and Hades. If he can find Zeus's missing lightning bolt within ten days, disaster will be averted. But can he do it?
Follow Percy's mythic adventures as he travels from this world to the Underworld to Mount Olympus in a heart-pounding modern odyssey that was a #1 New York Times bestseller.
