(Complete) Percy Jackson had his life straightened out. He was finally out of college, and now was living with his best friend, now girlfriend, Annabeth Chase. After a freak accident, Annabeth is left lying on the ground, stone cold. Percy thought his life couldn't get any worse. But then, after a night of disbelief, Percy wakes up with her curled at his side. The date was the same. Stumbling through time, Percy has to find a way to save her, as well as figure out who keeps killing her. And how he was replaying the same day over and over again, Annabeth getting killed each time. Who did this to him? Is it a blessing? Or a curse? (Warning: May cause feels)

Percabeth high school AU- Annabeth Chase, a perfect girl with a perfect life. She's popular, pretty and respected throughout the whole school. Cue Percy Jackson. A widely mocked, annoyingly attractive troublemaker with a slightly unhealthy taste for black clothes. These two polar opposites are just what the other needs to flip each other's worlds upside down and watch the chaos it causes... -Any pjo/HoO characters unfortunately don't belong to me but to Rick Riordan and the cover art is not mine.-

"You can't seriously expect us to go to a school for magic!" "You want us to what?" ~~~~~ Dumbledore sends out a distress call to the demigods. Voldemort is back and the gods made the mistake last time to refuse the wizard's call. Chiron sends Nico, Will, Thalia and Percy to go protect Harry Potter, the targeted wizard who Voldemort wants dead. The demigods must protect and defend Hogwarts from the dark wizard, but keep their identities as demigods secret at all costs. No one must know because it could put them in danger. But the golden trio keep persisting that the new students are up to no good. They make the secret terribly hard to keep.
