I l ike your story so far...
Where are going with Remus? IS he going to be a brainwashed Dumbledore follower or will he join HArry?
I like the idea of the ritual adoption and just wish that Sirius had done it when he was alive instead of arranging it for after his death.
The two girls are a great change from the usual Hermione or Ginny pairing too. Good job there. now all he needs is to get Draco and Blaise on his side to help get the dark sided kids.
Update Soon
