Karen is just an average thirteen-year-old from New Jersey who loves to play video games with her friends and watch movies with her mom. But when she moves to Greece to live with her eccentric, mysterious father, Zed, suddenly everything she thought about herself—about life—is up in the air. Starting a new school can be difficult, but starting school at Mt. Olympus Junior High, where students are gods and goddesses, just might take the cake. Especially when fellow classmates start getting turned to stone. Greek mythology . . . a little less myth, a little more eek! And if Karen’s classmates are immortal beings, who does that make her?

Karen and her new friends descend into a forgotten maze beneath Mt. Olympus Junior High in search of an online troll by the name of M1N0T4UR who has been ruining Karen's games with her friends. When Karen moved to Mt. Olympus, she certainly didn’t expect to start junior high with a bunch of gods and goddesses—let alone discover she’s a demigoddess (who doesn’t yet know her powers)! Having recently joined the school newspaper, Karen decides to investigate a mysterious online troll that goes by the moniker M1N0T4UR. This leads her to a treacherous maze beneath the school where she and her friends must complete a set of phases to leave the labyrinth. The stakes are higher than ever and a wrong move could lead to some terri-BULL consequences.
