What good romantic vampire books or graphic novels would you recommend for my girlfriends sister? She likes the "good vampires" not the gory type.

"Twilight" by Stephenie Meyer. Very romantic novel.

"The Historian" by Elizabeth Kostova. I read it earlier this year - wonderful book, especially if your sister enjoys history.

"The Historian is a 2005 novel by Elizabeth Kostova about a quest, reaching through the past five centuries, for the historical Vlad the Impaler. The novel, Kostova's first, appeared on the New York Times bestseller list during the summer and fall of 2005 and it was named the 2006 Book Sense "Book of the Year" in the Adult Fiction category. It's been published in 28 languages. "This book is undoubtedly the most suspenseful book I have ever read and I will soon read it again. Kostova's unique way of narrating is intricate in its own way." says Kristelle Baysa of the New York Times.

While nominally a modern re-telling of the Dracula story, The Historian delves deeply into the nature of history and its relevance to today's world, as well as serving as a cautionary tale on the historical antagonism between Western Civilization and Islam."

There's the ones by... Stephanie Meyer (I think that's the right name) that are fairly popular. There's also a series by Kim Harrison that isn't straight romance, and deals with more than just vampires, but it does have romantic aspects and a continuing romantic storyline. Very good books, in my opinion.

Any of the Ann Rice books.
