Just a different version of Demigods goes to Hogwarts. When Percy Jackson goes home to spend sometime with his mother. Something happens that will change his life. There were people with a tattoo on there arms. Who are these people? What are they here for? Read to find out! Cringe description IK. Just some twist and turns in this one. I have so many book ideas and I just have to write them down (explanation for why there are so many books) Anyone who have an actual plot line for this please tell me!
