The Lightning Thief is all about identity and about discovering identity. At the beginning of our narrator's tale, Percy Jackson doesn't yet know who his father is or that he has any special powers of any kind. He thinks of himself as a "bad kid," one who always gets into trouble. Over the course of the story, however, he learns things about himself that he never thought possible. What he thought were weaknesses (his dyslexia, attention deficit disorder, and knack for attracting trouble) turn out to be the markers of a demi-god, and a particularly powerful one at that. His identity is tested when he must make hard choices (i.e., deciding between staying within the safe walls of his camp or returning to NYC where monsters are sure to find him). With every choice Percy makes, he becomes more himself.
