Hey, I’m writing a book about vampires. So if there’s anyone who knows a lot on the subject (or preferably is one or claims to be one), could you please e-mail me at tapedblue@yahoo.com. A few things I need some info on:
Nocturnal-Sunlight weakens
Retractable fangs
Superior strength
Blood diet (how much needed per night/week/month/ect.)
Becoming a vampire-Turning
Immortality
Sterility
Other types of vampires
Crosses, and anti religiousness, and supposedly evil
Garlic allergy
And anything else you can think of, that you think would work nicely for the book. Thanks.
