Haven’t read the Percy books yet. Movies are ok. I like the Greek Pantheon so... All good there.
Loved Nathan Fillion as Hermes. They even managed to work in a couple of Firefly/Serenity quips for his character.
Ana’s 10. Currently working her way through the last couple of Warrior books(http://www.warriorcats.com/) and is most of the way through the second book in the Inheritance Cycle(http://www.alagaesia.com/).
Sally (13) and her friends are really into the Warriors books. They do artwork and fan fiction and stuff. Anoreth was the same about the “Redwall” books.
I’ll request the movie from Netflix. The little boys (Pat is 12, James is 10, Vlad will be 8 on Thursday) all know their classical mythology.
