I loved this book!
i reckon that it was the best book in the series, but the only things that for me weren't cleared up (i probably just missed it) were the voices heard from the veil in dep. of mysteries (OoTP) and also how _____ isn't surprised or shocked to see harry, ron, hermione at Shells Cottage after they hadn't been seen by anyone or sent word to anyone of their being there. Only those at Shell Cottage knew.
