Percy Jackson is 12, dyslexic and ADHD, living in New York with his mother and his stepfather, Gabe. On a school trip to the museum, his math teacher turns into a Fury and attacks him. His friend Grover is a satyr, and Mr. Brunner is the centaur Chiron. They take Percy to Camp Half-Blood, where he learns he is Poseidon's son. Zeus accuses him of stealing the master bolt and gives him until the summer solstice to return it. Percy, Grover and Annabeth cross the United States to the Underworld. On the way they find out Ares tricked them, and the real thief is still to be unmasked.

ChangePercy is 12
In the book, Percy is 12. The 2010 movie ages him up to 16. The Disney+ series went back to 12.
In the book, Zeus's bolt is in the backpack Ares hands the trio, and Luke only shows his hand at the end of summer. In the movie, Hades finds the bolt hidden in Luke's shield.
In the book, the trio crosses the country to Los Angeles and fights the Furies, Medusa, Echidna and the Chimera. The movie skips part of that and puts a Hydra in the Nashville Parthenon.
Stepdad Gabe is abusive in the book. On the show, producer Rebecca Riordan said the cruelty was toned down because it would be harder to watch on screen.
No spoilersThe easter eggs give away parts of the title. They open once you mark it as seen.
