very nice! =D
I like that you give the friendship between Astoria and Hermionie a realistic basis, and how you see them with their children before Hogwarts. I also like how you have Astoria remain reserved around Hermionie at first.
I love mythology and you really wove this together well. I love how the two women have a secret and it brings them together in a way that nothing else would. As they cannot share their experience with their husbands I doubt very much that Draco and Ron will ever accept their unique bond though.
