ANTISOCIAL MEDIA is the eleventh book in the Gray Spear Society series which began with APOCALYPSE CULT. Marina has just become the commander of the San Francisco cell of the Gray Spear Society. She has a new team, a new job, a new territory, a new headquarters, and crushing new responsibilities. Her total lack of experience as a commander doesn't make the adjustments any easier. To make matters worse, a mysterious phenomenon is tearing apart the social fabric of the San Francisco Bay area. Marriages are breaking up, and abuse of all forms is on the rise. Marina and her new squad of legionnaires must find the cause before the violence becomes deadly. They must defeat an enemy who is smarter than any she has ever faced.
