I was inspired by a story called Vision of Eternity by twistedtxle.

An AU where the Big Three are kings who want to become immortal so they send their children out to find the Fountain of Youth. While Percy has found a hint as to where the Fountain is, a second child of King Hades-- a young boy named Nico-- finds his way on the his ship. When he is discovered by Percy's crew, he is given a choice: walk the plank or rot in the cellar. Soon, Percy finds himself at the Fountain of Youth before any of the other royal children. He returns to his ship with the Core of the Fountain, feeling as though he's finally made his father proud. That is.... until Nico steals the Core, wanting to prove to his father that he's not the useless young boy King Hades seems to think he is. With the Core gone and without a ship, Percy has lost his one clean shot at returning home to his father with his prize. Now he and the other children are hunting down Nico, who is determined to return to King Hades with the Core on his own. It isn't long before he's captured by Bianca, his sister and one of the best huntresses in all of New Greece, where she steal the Core and throws him once again in the cellar. However, when Percy kidnaps Nico one night, under the impression that he still has the stone, the tables turn and the Sea Prince finds himself developing feelings for the Son of Hades. Will he be able to steal back the Core and return to his dad alone? Or is he going to need the help of someone who he knows can't be trusted?

BoyxBoy Percico "Say it!" I repeated. "Tell me what you actually think of me! You're just like everyone else, Jackson, I know it! Just admit it-" Percy let out a strangled noise and suddenly, I ended up on the rough grounds of the forest. My wrists were gripped in his hands tightly, pinning me down, as his black hair stuck to the sweat on his flushed tanned face, and mine to my pale cheekbones. My back ached, but my anger triggered pain was stronger. "Everything is WRONG about me." I said through gritted teeth. "I might not be a real ghost or a lost soul in my father's realm, Percy. But up here... I might as well be." ~It's a long journey to love. Especially if you run away from it.~
