Dani wants more than anything to be accepted by the gids of Olympus, over which her father, Zeus, holds dominion. Kaya naman nang magkaro'n siya ng chance na maging immortal, kinuha niya 'yon, not knowing that she'll have to betray a friend to get it. Stacy is happy being left alone on dry land, away from her medding father, Poseidon, god of the oceans. Pero nang magbadya ng coup d'etat ang mga minor gods laban sa tatay niya at sa ibang major gods, she reluctantly teams up with the other demigods to prevent a war on Olympus. Yda, anak ng god of the underworld, can barely stand her boyfriend Cato's thirst for battle. She should've known better than to date a son of the war god Ares, but then again, Cato should've known not to break the heart of Hades' daughter in the first place. They look like us, They act like us. They live among us. But they are nothing like us at all. They are the daughters of the three most powerful gods of Olympus. They are demigoddesses.
