The hardcover edition of the first book in Rick Riordan's thrilling middle grade series, filled with magic, Greek mythology, and plenty of monsters

Percy Jackson is about to be kicked out of boarding school again--he can't seem to stay out of trouble. Is he supposed to stand by while a bully picks on his scrawny best friend? Or not defend himself when his teacher turns into a monster and tries to kill him?

Mythical creatures seem to be walking straight out of the pages of Percy's Greek mythology textbook and into his life. What's worse, he's angered a few of them: Zeus's master lightning bolt has been stolen, and Percy is the prime suspect.

Percy and his friends Grover the satyr, and Annabeth, the demigod daughter of Athena, must find and return Zeus's stolen property and bring peace to a warring Mount Olympus. They travel cross country to the gates of the Underworld in Los Angeles, facing a host of enemies determined to stop them.

With millions of copies and over 10 years spent on the New York Times bestseller list, Percy has also become a movie, a Broadway musical, and now a Disney+ series. He continues to find fans in classrooms and libraries across the world.
