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.

Part 2 of Drowning in the Siren's Song. Percy learns that hiding won't hide him anymore. Just being himself has earned him enough power to garner the attention of the Gods. And for a Siren capable of influencing anybody with songs and is blessed by nature, his rarity is sure to bring more danger than just monsters. Now armed with the learnings of both Greeks and Romans, he tries navigate his messed up life, doing anything and everything to prevent himself from ever meeting the Gods and getting involved in their problems.
