Percabeth

You were adopted in the Jackson family quite a long time ago, probably three years. Little did you know that they weren't just humans, they were... Try to found out

You and your step siblings came back home. It was last day of school before summer holidays. That means that your step siblings are going to some weird camp (that you were forbidden from!) for whole summer and you will stuck here, with your "amazing" parents, aka Annabeth and Percy Jackson. As Annabeth and Percy were excitedly talking to their kids about some stuff (that wierd camp, probably), you went upstairs to your room, completely ignored. It's quite logical that your step parents loved you less your step siblings. They were biological after all.

Plus to that you were introverted, maybe even traumatized child. Maybe you were punished for talking before, or maybe just don't see any reason to talk. Since you were in one class with Charlie, your parents didn't need to ask you about anything according to classes. School news were also open to them since Cast was school president. Ethan was good in math and has won in a lot of olympiads. And then there was you. Absolutely nothing special, at least that's what you thought**
