A mortal Greek boy meets a goddess. She teaches him about real Gods and Goddesses, she protects him as monsters and God's come at them.
(this story takes place in Ancient Greek. And please don't take any relation to Greek Gods not being real for any of those, Hellenistic people. I love everything about Greek Mythology, I just had this idea and started to write it.)
