Persephone and her friends must rescue Athena from the evil King Hephaestus, who has turned Athena into a statue and hidden her in his massive treasure room.

"Aphrodite and Persephone are on a quest to find another missing jewel from Sparkle City, this one an emerald. On their search, the friends find themselves in a new land where a friendly, flying purple dragon might hold the key to helping the girls find the missing treasure!"--

Seeking to become immortal like the other Goddess Girls, Medusa searches for a magical necklace, an effort that is compromised by her mean reputation, her snaky hair, and unexpected consequences.

Goddess of the hearth Hestia feels invisible at Mount Olympus Academy.

Artemis, Aphrodite, Persephone, and Athena organize their own girls-only Olympic games at Mount Olympus Academy, but crush-stealing Amazons, a winged horse, and a kitten named Adonis complicate their plans.

As PERSEPHONE's mom encourages her to do, she often "goes along to get along" instead of doing what she really wants. But when she meets Mount Olympus Academy bad-boy Hades, she finally feels she has found someone with whom she can be herself. He's the first person who actually listens to her, and she finds herself liking him, despite the fact that the other goddessgirls think he's bad news. But if he makes her feel so special — and she's so comfortable...

With some extra magic and the power of friendship, Artemis and Orion help each other on their respective quests.
