I have read a lot of vampire/werewolf or just plain fantasy stories sometimes on the basis of it helps provide thought provoking material for inspiration when I've been writing. Mostly however for pleasure. I've just never read the Twilight Saga frankly it would not be enjoyable for me. I've read the Laurell K Hamilton books (some of them at least theres like 17 and counting in the Anita Blake series...frankly they were entertaining at first but grew boring fast) which are essentially a more adult grown up version of Twilight from what I've seen of the films, they have a crap ton of sex involved and most of the descriptive work is of the most graphic nature. Imprinting is common to most Werewolf fantasy. Imprinting is possible in real life though not in the context meant by Were creature fantasy.
