Vampirita, a series of novels about an astronaut vampiress, has attracted a huge following at X—and none moreso than Torrey and Terri. The next installment of the series will be released in a fortnight, and until then, fans can audition to star in the next book. The girls start to build projects to win the auditions, but every time one is finished, it gets sabotaged. The main suspects are two members of a rival novel's fan club, however, the evidence seems to point to neither of them.
