I read this one the other day and for some reason didn't comment on it...
This was wonderful and hot. I loved the side of Bill/Neville. I am even intrigued enough to read some more of the Ron/Pansy and Hermione/Lucius... I normally don't have any need to read het, but I would if you wrote those pairings.
Harry/Severus/Draco are fast becoming a group that I am looking out for to read more. *goes off to read more*
