Percy Jackson

Percy Jackson is the protagonist of Rick Riordan’s fantasy series that begins with *The Lightning Thief*, published in 2005. His full name is Perseus Jackson, and he is the son of the Greek sea god Poseidon and the mortal Sally Jackson. At the start of the series, Percy is twelve, lives in New York, and has a history of changing schools and struggling with dyslexia and attention-deficit/hyperactivity disorder. The story gives those traits a mythological explanation: his mind is adapted to ancient Greek, and his alertness suits a demigod’s dangerous life.

In *The Lightning Thief*, Percy discovers his parentage after being accused of stealing Zeus’s master bolt. He travels west with Annabeth Chase, daughter of Athena, and his friend Grover Underwood, a satyr, to find the bolt and prevent a war among the gods. The journey takes them through contemporary American locations reimagined with mythological dangers. Percy eventually learns that the theft was part of a scheme involving Luke Castellan, a son of Hermes who serves the Titan Kronos.

The next books follow Percy through escalating conflicts. In *The Sea of Monsters*, he searches for the Golden Fleece, which can heal the magical boundary around Camp Half-Blood, the refuge for Greek demigods. *The Titan’s Curse* introduces the Hunters of Artemis and brings Percy into a struggle involving the goddess’s missing companion, Annabeth, and a prophecy about a child of the Big Three gods. In *The Battle of the Labyrinth*, Percy and his friends confront an invasion route through the ancient maze beneath the United States.

The series’ central prophecy reaches its climax in *The Last Olympian*. Percy turns sixteen as Kronos’s forces attack Manhattan and the Olympian home on Mount Olympus, which Riordan locates above the Empire State Building. Percy plays a decisive role in defending the city and ultimately helps defeat Kronos, but victory depends on more than his combat skill: he offers Luke a chance to make a different choice. Percy also refuses the gods’ offer of immortality, asking instead that they recognize their demigod children and claim them.

Percy returns in Riordan’s sequel series, *The Heroes of Olympus*. In *The Son of Neptune*, he wakes at Camp Jupiter with his memories largely missing and joins Roman demigods Hazel Levesque and Frank Zhang on a quest to Alaska. The books connect Greek and Roman aspects of the gods and eventually reunite Percy with Annabeth. Across both series, Percy is characterized by loyalty, humor, and a willingness to challenge divine authority, especially when the gods neglect their children.
