Loyalty and Heroes

Persephone Jackson has done it all. Prophecy kid, child of the Big Three, Praetor of New Rome, Hero of Olympus, survivor of Tartarus... There isn't a soul alive who doesn't know who she is and what she's done. Well, at least for those aware of the mythological world.
Her fatal flaw is personal loyalty, and it's cost her a few times before. But this takes it to a whole new level. After going to Tartarus again, this time on her own, she gets back to find her family gone and the gods want her to be a goddess again. But this time, they aren't taking 'no' for an answer.
Persephone is done. Done with the gods, done with monsters, done with the whole of Greek life. She drops off the face of the map and leaves the mythological world behind, only keeping in touch with Nico, her cousin who's been through a lot of the same horrors she has.
She changes her name to Celestia Bell and starts fresh, getting a simple job as an executive assistant that turns out to be a bit more complicated than she first thought. Turns out the job wasn't just for Tony Stark, but for the Avengers as a whole.
Her new life is different, but for the first time, she feels normal. So, what happens when her past shows back up? Will the Avengers find out that there is more to Celestia than meets the eye? Will she get dragged back into the world she left behind? Or maybe, just maybe, can the daughter of Poseidon find everything she never knew she wanted and be truly happy for once?

A/N: In this fic, MGCA does not exist. It's a great series, but it doesn't work with my plans. Also, the timelines don't totally sync up, but let's imagine they do. Just shift the PJO timeline a bit to line up with the MCU timeline. And to be very clear, I am not Rick Riordan or Marvel. All things PJO belong to Rick Riordan. All things Marvel belong to Marvel. All I own is my own plot, characters, and writing. Feel free to comment or DM me your ideas. I'd love to hear them!
