27 parts Ongoing The Great Prophecy has been fulfilled, but the gods' war is far from over. A fragile peace hangs over Olympus like a fraying thread - and when that thread snaps, the entire world could fall with it.
When an ancient oath sworn by the gods themselves begins to unravel, Percy, Theo, Annabeth, and the rest of the Seven are thrust into a perilous journey that spans both Earth and the skies. Shadows stir beneath the ruins of lost temples, whispers of betrayal ripple through divine halls, and an unstoppable force begins to awaken - one older than the gods, older than Olympus itself.
Theo's mysterious parentage takes center stage as secrets long buried come to light, and Percy struggles with his growing feelings for him while navigating prophecies that hint at love becoming a weapon... and a curse. Friendships are tested, loyalties strained, and the line between gods and monsters blurs as the heroes race against time to prevent an oath-breaking that could doom them all.
With new enemies rising, impossible choices to make, and a storm brewing that even Zeus fears, Percy and his friends must decide: how much are they willing to sacrifice to protect Olympus - and each other?
In this heart-pounding continuation of the saga, danger comes not just from the monsters they fight, but from the promises the gods themselves failed to keep.
