Despite what her mom thinks, Cassie has lots of friends—they just all happen to be online, where she can talk to them about her beloved favorite show, Riverview, and get their feedback on her fan fic WIP, starring Jessica, her very own hot vampire OC. But her fic writing persona is revealed to the entire school when her former best friend finds it and can't resist reading some of it out loud to their classmates. Cassie thinks things can’t get more humiliating, until her very own Mary Sue pops right out of her fic to save the day—or make it much, much worse.
