Athena has always been above average. She's never quite fit in at Triton Junior High, but who would've guessed that Athena is actually a goddess? Principal Zeus's daughter, to be exact. When she's summoned to Mount Olympus Academy, Athena thinks she might actually fit in for the first time in her life. But in some ways, school on Mount Olympus is not that different from down on Earth, and Athena is going to have to deal with the baddest mean girl in history - Medusa!
Athena lived with her best friend Pallas and her parents since she was a baby. She always "yearned to know who her parents were". One morning a magical piece of papyrus flies through her bedroom window, informing her that she is the daughter of Zeus, and a goddess. She spends the rest of the day packing with Pallas, one suitcase carrying all her textscrolls and invention ideas. When morning arrives, Hermes arrives with a chariot, dropping Athena off at Mount Olympus Academy. Being parched, Athena drinks from the "water fountain", which is actually nectar, and her skin shimmers gold.
Athena goes to the office, meeting the "Nine-Headed Lady", Ms. Hydra. Athena chooses Hero-ology, Spell-ology, Revenge-ology, Beast-ology, and Beautyology. She wants to learn as much as she can, and is in a rush for her class. Three girls in the courtyard catch her attention, which later turn out to be the Goddess Girls, the most popular goddesses of the school. Pandora is the first student to talk to Athena, who asks lots of questions. She later turn out to be Athena's room-mate. Aphrodite and Athena meet during this time, both having Hero-ology together in room 208.
Mr. Cyclops teaches Hero-ology, and the students' assignment is to choose a hero and guide them. They are scored on manipulation, disasters, and quick saves. During the middle of the class, Athena is called down to the office by her father, Principal Zeus. Medusa, who seems to hate Athena, calls her a "Principal's pet". Feeling embarrassed, moreso that people are staring at her, Athena heads down to the office, which is incredibly messy. When first meeting, Zeus looks intimidating with his height of nearly seven feet tall, bulging muscles, and piercing blue eyes. Athena finds out that her mother is a fly. Pheme, the goddessgirl of gossip, eavesdrops on the conversation and spills what she heard to her group of friends, which includes Medusa.
When lunchtime arrives, Athena finds out about the invention fair, which she considers entering. Poseidon, the godboy who acts like a flirt, makes an offers to "let her" be his assistant. Athena is miffed by this, rejecting him. She then walks away and spots Aphrodite and the other two goddessgirls from earlier. Aphrodite suggests joining the Goddessgirl Squad which cheer on the Fightin' Titans, Mount Olympus Academy's sports teams. Aphrodite introduces the two girls as Persephone and Artemis, and later all of the four become friends.
After school, Athena goes to her dorm room and meets Pandora. As she looks at her sketches of inventions, Pandora asks many questions. A moment later her inventions begin raining down on earth, because she did not block her brainstorming. Feeling dejected about her first day, Aphrodite, Artemis, and Pandora comfort her.
During her first period the next day, Athena guides her hero, Odysseus. The class turns out to be on half - one side Trojan, and the other Greek. Medusa's hero, King Menelaus, is Odysseus' boss. Athena is on the opposite team of Aphrodite and Poseidon. Later in the class, it turns out that Medusa has a crush on Poseidon, which explains the dislike for Athena. Poseidon's side try to keep the Greek side from getting into Troy. Thinking of an idea, Athena puts some of the heroes in her toy horse, Woody, and sends it as a "gift". Poseidon accepts it, unaware of the trickery.
After school at the Goddessgirl Tryouts, Coach Nike and her assistants, which are the Nine Muses, split the girls into clusters for the final squad tryouts. Athena attempts to mediate the relationship with Medusa. However, Medusa and her sisters tease Athena with a "fly cheer", to which Aphrodite, Artemis, and Persephone intervene and stick up for her. After tryouts, a student catches their attention about their heroes in Hero-ology class, who are fighting without them. As several including the Goddess Girls head into Mr. Cyclops's room, they discover the horse and its secret compartment.
The next morning one of Athena's inventions is missing. Snarkypoo, or Snakeypoo, as she misspelled it, is supposed to turn any snarky words they think of to stone before they can be spoken. When heading to her first class with Aphrodite and Artemis, they notice a new girl marble statue who looks familiar. Medusa turns out to be absent from Hero-ology, and automatically they put the pieces together that it coincides with the marble statue.
The shampoo Snakeypoo turned Medusa's hair into snakes, as well as the ability to turn any mortal to stone. Medusa turns Artemis' three dogs to stone. Athena tricks her by Poseidon telling Medusa she has something in her teeth. Offering a mirror, Medusa takes it from Athena and turns herself into stone by reflection.
After reversing the spell of Pandora and the three dogs, they leave Medusa as a statue until the next day of the Invention Fair. When the Fair arrives, Athena does not enter, realizing that Poseidon's invention, the water park, is way better than hers. Despite this, Athena wins first place, with her invention of the olive. When her inventions rained down on Earth, the mortals used olive as an ingredient and for oil, and perfumes. Poseidon wins second place, and when asked what they want, Poseidon proposes a list: a chewing gum named after his trident, be appointed as Earth's official water park designer, and statues of him placed in water fountains. Athena wishes for her mortal friend Pallas to visit. Pallas appears in her PJs, and is introduced to Athena's friends. When Pallas asks Athena if she was happy and fit in, Athena assured her that she was and did.
