I must admit that 'Interview With The Vampire' by Anne Rice is one of the best and most beautiful written books that I've ever read. However, since the Vampire thing is blown into teen pop culture, I fear the rest of the genre might be overshadowed by i.e. the Twilight series. I would guess that itīs risky to put it out there at the moment, but who knows? I guess it's all up to you, and how confident you are. If your book is good enough, you might as well catch the wave and go for a ride.
