I've read this too... and that one of the other of them ripped off The Vampire Diaries... but after having read all the books in question... and also being a fan of Dracula and The Vampire Chronicles... I think it's pretty much all Bull S... There are similarities in every vampire story I've ever read... even Dracula has a love triangle... and Louie became a "vegetarian" vamp...
If all of this was so true then I think the authors of these other books would be going after Stephanie Meyers. I surely do not see that happening since she has made millions of dollars of her book sales and also off the movies. I agree with Caitlyn it is all utter Bull S***.
