At twenty-one, Cassie is in a dead end job and has just been dumped, whilst her friends are succeeding at school or their careers, and compared to her, are generally winning life. On a whim, she hands the reigns of her decisions over to Twitter, and at first her followers seem to be making her life better. However, as the instructions continue, they become increasingly strange. Soon she finds herself held at ransom, forced to commit crimes for an unknown party who seems to be stalking her at every turn. With the lives of her friends and family at risk, she has no choice to play along. But this isn't the first time this has happened to someone like her. And if she doesn't find out who's pulling her strings, she won't be the last.
