A new group of campers has arrived at Camp Half Blood, one of which in particular has been revealed to be the center of a third Great Prophecy, and the key to stopping a massive conspiracy against Olympus. Marked with the parentage of a forgotten destroyer, can he overcome his father's reputation, redeem his brethren, and take his place as a hero?

Kratos and Loki survived the first Ragnarök, breaking another world in the process. Fates around the world banded together and suppress the tales of their existence. Atreus and Kratos enter a self-exile as a way to spare the mortals of suffering. All was fine for three millennia until one problem popped up: Atreus had a son during his escapades and he joined the half-blood camp.
