The War Gods Didn't See Coming

When Annabeth Chase joins the Hunters of Artemis, Percy Jackson is left behind-not abandoned, but unfinished. He still saves Olympus. Still fulfills the prophecy. Still becomes the hero history remembers.
But heroes grow up alone.
At the end of the Titan War, Percy accepts immortality-not for glory, but because everyone he loves keeps leaving. As a god, he chooses a quieter domain: loyalty, unbroken oaths, and lost children. He builds a place no god ever has before-Cabin 0 at Camp Half-Blood, a sanctuary for the unclaimed, the forgotten, and the kids the Olympians never bothered to see.
Centuries pass. Mortals age. Percy doesn't.
When demigods begin disappearing-not dying, but being erased from fate itself-Percy discovers an ancient force older than Olympus is feeding on divine neglect. Letheion, the embodiment of forgotten children and broken promises, is growing stronger. And it hates Percy Jackson.
Because Percy stayed.
As Olympus hesitates, trapped by politics and fear, Percy breaks divine law and enters the Loom of Fate itself, ripping lost children back into existence. The seas rise. The sky floods. Gods remember what it feels like to be afraid.
Annabeth, still a Hunter, still immortal, returns to fight beside him-only to find the boy she loved has become something far more dangerous. Together, strategist and storm must decide what loyalty truly means, and how much a god should be allowed to protect.
In a war where memory is a weapon and love refuses to die, Percy Jackson may have to give up the very godhood he never wanted-just to make sure no child is ever forgotten again.
