Percy was laying down on the floor. His fight against the giants wasn't going too well. He has been delivered a beating from his enemies. He could hear Zeus' thunder rumbling faintly. Annabeth had disappeared. She said she would be right back, but it's been a long time since she left. Frank had turned into a tiger running through Gaea's troops. Jason and Piper were flying trying to reach the awakening Gaea. They had to stop her or everything would be lost. Leo was waving his Wii controller into the giants. Gods and giants were fighting like never before because everyone knew what was on the line.
Percy got up and pressed the button on his pen. The celestial bronze blade, riptide appeared in his hand. He charged with all his might and struck down a monster after the other.
Suddenly, the earth started shaking and there was a loud roar. From the soil, the terrible titan Kronos formed.
"Percy Jackson! I have returned to claim my revenge! You will be destroyed this time," he yelled.
He started marching towards him, but he was interrupted Tyson, Percy's half brother and general of Poseidon's army was riding one of Hades' hounds, Cerberus. And with him were his best friends, Annabeth Chase and Grover Underwood.
"Ha!" laughed Kronos. "You think a hound will defeat me?"
Grover smiled. "We didn't only get a hound."
Then, birds started singing and flying. They came together and blocked everything behind them from being seen. When they moved, there was a bearded man that looked like he had no face. When his looked up and revealed himself. It was Pan!
Percy couldn't believe his eyes. He had seen the nature god die with his own eyes.
After that, something amazing happened. Pan raised his hands and the surrounding trees took life and charged straight into the battle. Kronos was able to draw the trees away, but they were too many. They neutralized the titan and he went back to the ashes.
Tyson, Grover and Pan went into battle. Percy called the six other demigods to talk about the plan.
"We need to get to Gaea before she awakens, and fast," said Jason.
"But how?"asked Hazel.
Jason looked at Leo and said "Leo, start the ship."
In less than a minute, the Argo II started and the face of Festus shot fireballs at the giants. Many didn't survive.
"Get off the ship and help the gods. I'll take it from here," ordered Leo.
The rest obeyed. But it was too late. Gaea had awoken.
"Foolish children," she said. "You thought that you would win? I have already won now that I have awoken."
"It's not over," muttered Leo. He charge Festus right into the earth goddess and hit her in the face and fell down. The earth started shaking and every single monster and giant did too. They fell down on the ground, dead. The war was won. Olympus has been saved.
Everyone was celebrating except one person. After the Argo II hit Gaea, it fell back and crashed into pieces. Leo was lying on the floor, probably dead.
The six were looking down at him, in tears. Leo had sacrificed himself to save Olympus.
Zeus, Poseidon and Hades looked at each other and walked to Leo. Holding hands, they concentrated on Leo and something unbelievable happened. From the sky came the thunder and rain, then came the fire. They collided where Leo was lying and disappeared. Leo opened his eyes looking at the gods, then smiled. The six demigods jumped at him, hugging him and laughing. The gods looked at the happy demigods and walked away back to their well-earned kingdom.
The demigods decided to throw a party at Camp Half-Blood and to invite the Romans, too.
The Romans accepted the invitation.
At the end of the party, the fireworks started and Annabeth kissed Percy, Piper kissed Jason, and Hazel kissed Frank. Leo stood there, lonely and sad. One of Aphrodite's daughters was sad for Leo because he was the hero and no one was there for him, so she came to him and congratulated him for his achievement. They spent the whole time talking, and at the end, they held each other's hands and kissed. Finally, Leo had found himself a girlfriend after the many years of trying, and they lived happily ever after.
