A child born from a miracle was named Perseus Jackson. His mother, a loving mortal with the gift of sight, brought together both aspects of the Ocean, combining Poseidon and Neptune into a single being, born from her love. Something never done before, nor heard of. A child armed with the powers from both personas of the sea, knew nothing of the truth. He'd inherited, not only the power to subjugate water, but to charm with his songs like the tides of the sea, an ability exclusive only to the rarest children of Neptune. He was a siren. After unleashing his powers one day, the world realized that he held much greater power than once perceived. But he had to hide it. Such authority was unwelcomed in a world where survival was a fight. One slip up and they would know that he was not normal, even among children considered abnormal- Demigods. It was the beginning of a silent song. It could heal; it could destroy. And the melody was controlled by Percy Jackson, the one demigod who wanted nothing more than peace and quiet.

*NOW ON AO3 AS WELL* REWRITTEN VERSION 2025 (old version can still be found in My Stories) *Future chapters under major plot hole construction, irregular update (As of May 10, 2025)* Seven years ago, she was a runaway determined to put Gotham City behind her. Seven years later, she returned, a new threat has fallen on the mortal world, and it is up to her and her allies to stop it. The world didn't know her as Persephone Jackson, the adopted daughter of Bruce Wayne; nor do they know her as Nightingale, the Girl Wonder, the protege to the Dark Knight along with Robin. She's now known as Riptide, an agent from the Celestial Division of the Agent of Olympus - a newly emerged organization that specializes in dealing with a certain new kind of 'vermin'. And although she had long put her unfortunate past behind her, it seems that the past wasn't quite done with her just yet... (Cover generated by AI, cause I can't draw for the life of me)

For once in Percy Jackson's life everything is peaceful, but when tragedy strikes, he is left alone. His closest friends and family all died in a seemingly random monster attack and his mom and Paul died in an accident. Consumed with grief, he goes to the gods wishing for death. Instead, they offer him a new purpose in life as Guardian of the Hunt. Percy accepts the opportunity to create a new family and regains some of the happiness he lost. But what if the monster attack that killed his friends, and Annabeth, wasn't random? Suddenly, Percy is caught in another war and is forced to face another enemy. Now, not only will he have to be the Guardian of the Hunt, but the Guardian of his home and, hopefully, find peace, once and for all. *Disclaimer for whole story: I own nothing but the plot and a few minor characters. Everything else belongs to Rick Riordan.* *Entire story will be Percy's POV unless I say otherwise.* *NOT PERTEMIS* *COMPLETED* #Wattys2017
