Percy Jackson, Harry Potter, and the Prisone...
Last year, Perseus Jackson discovered that he was a demigod. His father was not some ordinary man as he had originally thought. Instead, he was the son of the one and only Poseidon, the Greek god of the seas. However, his adopted brother, Harry Potter, had no idea about Percy's true parentage. The Headmaster of their school, Hogwarts School of Witchcraft and Wizardry, had forbidden Percy from telling anyone. Thus, he was forced to go to America, where he would be safe during the summer outside of school, without telling anyone where he was really going. Percy leaving made Harry angry and resentful. After all, he would be forced to spend the summer with the abusive Dursleys while Percy went off and had fun in another country. However, when Percy returned to school to join his brother and friends, he found out that his brother was in grave danger. An infamous mass-murderer by the name of Sirius Black had escaped Azkaban prison. And he was out for blood.
Note that I do not own anything that was created by J.K. Rowling or Rick Riordan. I only own some of the plot and the occasional person or place that I may create.
My updating schedule is completely random; don't count on consistent updates.
Another note, I edit as I go along so there may still be some grammar and spelling problems.
