A change in time for better or worse

This is about Harry Potter, I just thought this would be a good title. This is a story about how Sirius and Andromeda are the same age as James, Lily, and Remus. What if Remus had a cure? If Andromeda and Lily were the best of friends? If James and Lily don't hate each other? Bellatrix is just two years above the group and Narcissa two years below. All of this and so much more will be in this book. Ted and Nymphadora are twins so that's that.
