Fics like The Eternal Pair

And fate decided by parents' hands. Percy holds the sky so Artemis can fight. Zoë dies anyway. And when the Olympian council votes on the boy who saved them, the last line of the prophecy turns out to mean exactly what it said. Artemis casts two souls into the stars — and does not leave them there. She binds them into one being, outside fate and beyond Olympus's reach, and swears that the day the Titans fall is the day the Hunt is done with her family. Five years later a new Great Prophecy names seven heroes. Two masked figures with mismatched eyes begin turning battles that should never have been winnable. They have a home nobody can find, a daughter nobody knows about, and a promise owed to a goddess who no longer speaks to Olympus. Gaea is only the war. Olympus is the reckoning.
