Percy Jackson, Son of Poseidon, Hero of Olympus, Child of The Great Prophecy, you could call him many things. One thing you can't say about him though, is that he's had an easy life. Before his life as a demigod even began, he was abused. Before he had even hit fourteen, he had seen innocent people die. He was in two great prophecies, and was the gods 's bitch, doing all their dirty work. When Percy fell into Tartarus, he started hearing a voice.
