A collective of mystery writers, known as the Society of Fibbers, has captivated thousands with their addictive podcast-catapulting each member into the limelight. But when one of their own is found dead under chilling circumstances, the remaining Fibbers realize their newfound fame may have painted a target on their backs.

Rebecca Stanchion, one of the group's co-founders, is convinced her friend's murder is a tragic case of domestic violence-until a sinister attempt on her own life shatters that theory and threatens her family. Meanwhile, Zach Hargrove, a fellow writer, becomes obsessed with the cryptic black cards left at both crime scenes. Each card seems to whisper a warning: the killer is watching.

Is this the work of a fan driven to madness, or has betrayal seeped into the heart of the Society itself? As an annual writers' conference approaches, Zach and Rebecca race against time to unmask the killer before the Society of Fibbers' headline appearance turns into a deadly final act.
