Rule 34

Hugo Award-winning author Charles Stross takes listeners into the near future for this breathtaking thriller. As head of the Rule 34 Squad, Detective Inspector Liz Kavanaugh keeps a close eye on Internet activity, monitoring whether people are participating in harmless fantasies or engaging in illegal activities. When three criminal spammers are murdered, it¿s up to Liz to determine how the victims were connected. If she can¿t figure it out, more people will surely die.
