While at camp half blood Percy finds out he is a demi-god and his father is Poseidon. Later on he is accused of stealing Zeus's lightning bolt and he has to go on a quest to find the missing bolt in order to stop a war between the gods.
After Percy's battle with Ares...He goes to the empire state building where Zeus lives and returns the bolt to Zeus. He sees his father Poseidon and he told Percy, "do not misunderstand me, whatever else you do, know that you are mine. You are a true son of the Sea God."
While on a field trip Percy Jackson gets in trouble with the math Teacher Mrs. Dodds. As she goes to punish him she turns in a Fury. Mr. Brunner the Latin teacher tosses Percy a pen that turns into a sword. He stabs Mrs. Dodds and she disappears. then as Percy and his mom are on vacation, Grover ( Percy's protector aka a Satyr) shows up and says it's not good to be in the real world he needs to go to Camp Half-Blood because monsters are after him. On their way to camp half blood a Minotaur shows up and kills Percy's mother. Percy then gets upset and kills the Minotaur.
Grover, Percy, and Annabeth go through many battles and rough patches on the way to get Zeus' bolt because they think Hades has it but they are wrong and it turns out that Percy has it in his backpack that Ares gave him. There is a battle between him and Ares and Percy wins.
After Percy left the Empire state building he went back home and his mom was there alive and well. He then went back to camp half blood and he was enjoying himself then Luke (one of his friends) told him that he was the one that stole the lightning bolt and Hades shield. After he told Percy he had a scorpion poison him so he could die but in the end Percy stayed alive.
