I really like this story.
Revenge for the Waesleys: Bond cumbice for Ginny, and take over the family
Please kill dumnle in an awesome way, (like what Sirius said for him to do)
What are you going to do about Hermione?
What about Bellatrix?
as for the spell you asked about i know it is in either The Heritage or The Witch's Secret both on ficdom
UPDATE SOON
