(Percabeth Fanfiction) PERCY was finally an adult. He was responsible for himself, and himself only, and could do whatever he wanted. With his new life going in a straight line, he could choose whatever he wanted to do. That was, of course, before the blonde broke through his apartment door and pulled him down a fire-escape. ANNABETH had never been normal. Not with the running and hiding, the fighting. When gang-leader Luke is after her once again, hoping to kill her because of the one piece of information that she overhead, and the one item that she now held in her hands, things start going downhill. She was doing fine in her plan to kill him, before the boy with sea-green eyes got in her way. LEO has always been an outcast. He was used to it, but it became the last straw when his long time girlfriend Calypso started seeing another dude. When his best friend and fellow runaway, Annabeth, gets in a spot of trouble, well, it's only right to help her. (Percabeth) (Leo and Annabeth BROTP)

(Currently Editing for Continuity and other such errors) Guardian of the Huntress The Guardians, and ancient order created by the gods with one purpose, one reason for existing. That reason? To protect the gods from their enemies. Each Guardian was assigned to and Olympian for life and was tasked with ensuring said Olympian's continued physical, mental, and emotional health. Such little information is known about the Guardians that mortals do not even know of them and demigods consider their existence to be a true myth. One of these Guardians, a son of Poseidon, was considered the greatest of all Guardians. A force to be reckoned with, the Guardian of Artemis, the Midnight Huntress with a silver bow, was nigh unstoppable. His name was Perseus Jackson, and this is his story.

What if Percy knew about his heritage from the beginning? What if he never knew his mother? What if Percy was the only male the Hunters considered acceptable? Find out in this story as Percy is raised with the Hunters of Artemis
