Writing stories about vampires doesn't have to mean spooky castles and bloody scenes. The sensual undertones of vampires open the door for stories focusing on vampire romance rather than gore. Writing a vampire romance novel involves more than putting two characters in a forbidden romance. It also requires strong plot development and fully-developed characters.
Study the vampire romance genre. Read as many vampire romance novels as you can. Stephanie Meyer's "Twilight" series and Shannon Drake's books are good examples. Note what you like about each book and what you don't like; this helps you from falling into clichés and can inspire you to put your own twist on the genre. Read more at: http://bookworldi.webs.com/
