When Percy sacrifices himself to defeat Gaea, everyone is left in despair. Gods, goddesses, demigods, Mrs. O'Leary, Blackjack, everyone. Even Hades, Dionysus, Ares and Artemis are depressed. Little did they know, their hero was watching them with sad eyes, unable to enter the underworld, but living as a ghost roaming the surface of the Earth. He's not completely dead, yet not alive either. The Fates have prepared a whole twisted fate for Percy, yet again throwing him into trouble. Only one thing can bring him back to the realm of the living before it's too late, and it's a nearly impossible feat.
The living demigods, gods, everyone has to become happy again, without their hero.
Percy knelt before three of the gods. His hair was messy and his skin pale. His eyes were red rimmed and puffy and his cheeks tear stained.
"Percy? What are you doing here so late?" Lady Hera asked.
"I have a request." Percy said in a croaky voice.
"Anything for the saviour of Olympus." Lady Hestia replied immediately.
"I wish to die."
When Annabeth breaks Percy's heart and turns everyone against him, he begs Artemis, Hestia and Hera to kill him. Not wanting their favourite hero to die, they give him a new purpose to live. As the hunts new guardian.
