For Alex, it was the Percy Jackson series, believe it or not, that sparked his interest (obsession might be a better word, but it has such negative connotations lol).
His dad read them aloud to him starting when he was 4 or 5. He’s gone on to read everything he can get his hands on regarding mythology. He discusses the subject with this command of the vocabulary and the history and the stories, but Alex has always done that, whether he knows an actual hill of beans about what he’s monologuing on about or not.
So I’ve learned to fact check his versions of everything, and gently (oh, so gently) correct him if he’s wrong.
He’s wrong about very little regarding the big picture and specifics of mythology, as well as how and when the different cultures’ own mythological histories and legends interact and crossover.
This leads me to believe that Rick Riordan stays very true to the classical interpretations in his books, as Alex does little “hard research” into the subject.
Anyway, it won’t be long before you can start reading them to your kiddos. :)
