This is actually a three-way crossover between Twilight/Vampire Diaries/NCIS, but the latter is more of a plot device. Bella has become a vampire, and running from her past she had become an agent, trying to do some good with her superhuman abilities. But your past always catches up with you one way or another. T for now, but might change later, depending on how descriptive I get.
