"Athena can't believe it's almost her little sister Hebe's birthday...or that it's been a year since Athena found herself at Mount Olympus Academy. It turns out Athena and her BFFs, the Goddess Girls, remember very different versions of Athena's first day at school. To see what really happened, they use a spell to travel back in time! The girls go back a year earlier but to ancient Rome instead of Greece--where they meet the Roman equivalents of themselves!...

In this ninth "Little Goddess Girls" story, young readers can join little Athena as she embarks on a wonderful seafaring adventure.

Athena learns that she is a goddess when she is summoned to Mount Olympus by her father, Zeus, and she must quickly adjust to her new status, make friends with the other godboys and goddessgirls, and catch up with all the studies she missed while attending mortal school.
