Mortal Kiss lets tweens get their vamp on this fall

Considering Zynga'sVampire Wars is home to 2.3 million users and the success of the "Twilight" series, we can safely say this vampire craze has surpassed "fad" status. Publisher Random House has teamed up with social gaming website Stardoll to get their slice of the bloody pie with an interactive story titled "Mortal Kiss."

Starting today, eight chapters of "Mortal Kiss" will be released over the eight weeks until Halloween when the final chapter will be revealed on the biggest day of the year for vamp fans. Stardoll, a social gaming website geared towards teenage girls, will allow users to vote on the outcome of key moments in the story and discuss major plot points as they happen.
