Help me make a BIG Vampy list!!!

So I have this big plan that I am hoping you will all help me with!  I am compiling a list of "vampire" books.  I plan for each entry to have a link to the authors web site so more information can be easily found regarding the novel or series. 

Now, I have A LOT of books with vampires as the main theme but I certainty haven't read them all by far so that's where you come in.  If you have a moment please share one or more of your favorite books or series that has a fairly significant amount of vampire "action." 

The reason I want to compile a list like this is a) I love vampires, b) I have run out of authors/series that have vampires in it and need new reading material, and c) I have spent time looking for lists such as this and have only found one or two good ones out there so I thought I would make my own (with your help of course). 

I am thinking this list should be organized in some particular way.  I could do a traditional alphabetical list by author, series, or genre, or do sub categories such as YA, Horror, Mystery, Erotica, etc.  If you have any ideas on how this list should be organized please feel free to comment with suggestions!  I will launch this list asap and continue adding to it as I discover more and more yummy vampy books!  Thank you for all those who comment and pass on suggestions :)
