The characters created by mastermind Joss Whedon will live on forever. Initially a movie (starring Kristy Swanson and Donald Sutherland) it wasn't until the series began that Buffy (and its subsequent spin-off Angel became really popular) Whether it's the thought of an attraction between a vamipre (Angel) or a vampire slayer (Buffy) or the lives of those surrounding them (better known as the Scoobies for those regular readers and watchers of the buffyverse). After all with a witch (Willow) a mean (yet sometimes loveable) Vampire (Spike) or all around good guy (Xander) not to mention the other regulars there's bound to be something for everyone.

For the most part these shows created by Joss Whedon have reached a cult like status and now even though shows like Buffy have gone off the air you can still not only read about them in paperback novel form or online stories,  even now their journey continues in Buffy Season 8 where creator Joss Whedon brings Buffy back direct from the ending of the tv series in his new comic book (from Dark Horse Comics).

A search of book stores or places like Amazon.com and you'll also find many Buffy novels that have been published
