These books are good, and they're really cool because I love Greek myths, but I don't think there's good role models because they turn Medusa into stone, girls tease Athena because her mom's a fly, etc. But here are my good things:
1. Greek culture is really educational, but Goddess Girls make it fun to learn new things about other, older cultures.
2. It has amazing descriptions, so you can picture the glory of Mount Olympus in your head without having to look at the cover.
3. Like I said, it is educational, but they put Greece and Mount Olympus into times like we experience so that we can relate to them better. These are good books to read to a class or to your kid.
Therefore, I recommend reading these books. They're amazing!
