'Percy Jackson and the Olympians' by Rick Riordan
Series of books.

 Rick Riordan’s trailblazing YA fantasy series kicks off with one of the best premises this side of the millennium: twelve-year-old Percy Jackson discovering he is the son of Poseidon. This revelation leads him to Camp Half-Blood, where Percy adjusts to his new identity and meets fellow demigod kids. Along with his friends Luke and Annabeth, Percy soon embarks on a perilous quest to recover Zeus’ master lightning bolt, the disappearance of which has thrown Olympus into chaos. And this is only the beginning of the gripping Percy Jackson pentalogy, which is chock full of nail-biting suspense and enthralling mythological adaptation.
