Here's one unsurprising result of the amazing, still not entirely understood Twilight phenomenon-- young adult novels featuring vampires are about to become required reading for studio execs. Already two producers, Michael Birnbaum and Jeremiah Chechik, have put up their own money to buy the rights to House of Night, a nine-book series featuring adolescent bloodsuckers.

As described by Variety, the books actually sound more like Harry Potter than Twilight-- vampires possess a genetic anomaly that only manifests at puberty, so when they turn into vampires they're sent away to the House of Night, a school that teaches them how to function as adults. Oh, and in this book, it's spelled "vampyre." No clue why.

The fourth book has just been published, which means there's an even bigger opportunity to create a publishing phenomenon if the movie is a hit (the Twilight series, on the other hand, is complete). There's , of course, no way to know if one vampire movie will do well because another one was a hit, but that won't mean producers won't try. Between Harry Potter and all these vampires, we won't be rid of supernaturally abled teens for a long, long time.
