True Blood is an HBO Series starring Anna Paquin and its based on Charlaine Harris's novels Dead Until Dark, A Touch of Dead, Dead and Gone etc.. You'll find that many of the themes are very similar to what is presented in the Twilight series. However True Blood is targeted to a more adult audience, and the series does a much better job at pulling you into the universe than Twilight did for me. The premise is that every day society has discovered that Vampires exist and are living among them every day. Thanks to the invention of synthetic blood called "True Blood" Vampires no longer need to survive on human blood and can purchase and consume to True Blood to keep them going. However, there's those who choose not to of course.
