Ick, the thought of getting your heart cut out, slowly, while concious... that sounds horrible. Good thing Voldemort trusts Snape so much. I'm glad you didn't dwell to much on what happened to Harry, his battered body implies enough.
Author's Response: Yes, does sound horrible- most things Voldemort commands are. You hit on the point I would make about Voldemort trusting Snape in the next review, so I won't comment on that, lol.
I do sometimes feel that authors overdo it on the torture and whatnot, because they keep going back to the point later. Do the torture and skip the result, or do the result and skip the torture, I say. Doing both implies sadism, if you ask me.
