Percy Jackson is a demigod son of the mortal Sally Jackson and the Greek god Poseidon. His mother, Sally, had also married a man named Gabe Ugliano, who died. She married him to protect Percy, as his foul mortal odor would hide Percy from any monsters. Later, she marries a man named Paul Blofis, who she really loves. Percy is the main protagonist and first-person narrator in the Percy Jackson & the Olympians series, and appears in every book of the Camp Half-Blood chronicles except The Lost Hero, The Dark Prophecy and The Burning Maze. In his most recent appearance in The Hidden Oracle, the seventeen-year-old Percy states that he and his girlfriend Annabeth Chase plan to finish senior year in New York before he heads to New Rome University.
