So this is a PJO/HP crossover. All rights go to Rick Riordan and JK Rowling. I do not own any of the characters!!!!!!! New Readers: I've started re-writing this story. Original chapters will remain available, but the plot has changed slightly so feel free to start reading at/after the Author's Note. All re-released chapters are titled with a "[v2]". Original summary: Percy's finally defeated Gaea, but the deaths that occurred along the way, and his trip to Tarturus still haunt him. In the midst of his mental struggles, Albus Dumbledore offers Percy a quest--protect Harry Potter. As Percy ventures into another world he hadn't realized existed, he learns that he has a much bigger role in the upcoming war against Voldemort than anyone could have imagined.

He couldn't wait to spend the rest of his life in peace, living in the Roman town with Annabeth, occasionally visiting the rest of his friends. It was going to be a good life. Or maybe not.

Meanwhile Harry is also having a hard time. There's been many things on his mind this past year. -A Defense Against the Dark Arts teacher with a personality like poisoned honey -A venomous, disgruntled house-elf -Ron as keeper of the Gryffindor Quidditch Team -Malfoy's annoying antics -The looming terror of the OWLs ...and of course, the growing threat of He-Who-Shall-Not-Be-Named and his newest addition to the family. A grandson named Percy. This story takes place after Blood of Olympus and during Order of the Phoenix. How will things end for The Boy Who Lived and The Savior of Olympus? ....

Takes place after the Deathly Hallows and the Blood of Olympus Percy Jackson thought he could finally live a normal life. He was going to fail high school, be the captain of the swim team, spend a whole, normal year with Annabeth. Yup, not gonna happen. Harry Potter has to redo his seventh year at Hogwarts. At least he gets to be with his best friends. Then some new kid shows up and he can't help but be a little jealous. He was the grandson of Voldemort and the girls were just falling at his feet. Even Ginny and Hermione were swayed by this boy. He was a death eater, and Harry could prove it. Luckily for him, the Triwizard Tournament was right around the corner. If the death eater was chosen, it'd be fun to watch him fail. Warning : Ron/Hermione and Harry/Ginny did not happen yet. Second Warning : Sirius, Snape, and Dumbledore are still alive. Just a disclaimer for the whole book : All rights go to Rick Riordan and J. K. Rowling Cover courtesy of @thatgirlariadne
