A character in Dracula, by Bram Stoker. Her full name is Mina Harker, nee Murray.

Published in 1995 (ISBN: 0-425-14359-7), Mina is a fairly short book (325 pages). Written by Marie Kiraly, it's a parallel to Dracula, told from Mina's perspective.

Over the course of several days, I skimmed it. It seems to be a fairly interesting book, although like many vampire novels, a lot of it degenerates into vampire sex. In fact, I was so intrigued by the book that I decided to perform a small experiment to determine its exact sex content.

I took a random sampling of pages from the book, counting how many of the pages contained sex (foreplay, sex acts, remembrances involving descriptions of sex, "fade to black" right before sex), and found that the book had a sex content of 62%.
