Percy was betrayed and disowned by the Gods and demigods. i know what your expecting. When does Percy meet Chaos and get sent back to Earth to face his old family after like 20 years. The answer is never. Instead of meeting Chaos, Percy goes home to his mom and stepdad, Paul. Turns out Percy has a 1 month old little sister. Sally lets him stay since he was a disowned son of Poseiden, which means he is mortal, which means he has no Godly scent. How does Percy fair after Sally, Paul, and his little sister, Jenny, are murdered and some wizards come knocking on his door, telling him that his Grandpa on his moms side is an evil wizard called Voldemort and he has a lot of magic potential? He thought the weird life was over after he was disowned. Guess the Fates still hate him.
