Athena the Wise (Goddess Girls, Bk. 5)

When a mortal named Hercules transfers to Mount Olympus Academy, Athena wants to help him fit in. Not only does Hercules need help finding friends and adjusting to life at his new school, but he must also complete twelve "labors" in order to earn a permanent place at the academy - and a shot at achieving immortality.

Athena's dad, Principal Zeus, takes an interest in the new kid and asks his daughter to secretly watch out for him as he tries to complete his tasks. It will take all of Athena's famed wisdom to sort out her own problems and help Hercules succeed!
