After her sister is murdered, a woman infiltrates a support group for serial killers in this biting queer feminist debut thriller, perfect for fans of The Final Girl Support Group and My Sister, the Serial Killer.

When Cyra Griffin’s younger sister is murdered by a serial killer, Cyra knows better than to expect justice from the hands of the police department. With the investigation already dying its own slow death, Cyra follows the blood trail and finds her own way forward. 

Using insider information (don’t ask) Cyra infiltrates a support group for serial killers by pretending to be one herself in the hopes of finding the person who ended her sister’s life. Proving herself to them comes at a cost, but it’s one Cyra is willing to pay in the name of revenge.

But the dangerous men in the group aren’t the only obstacle in Cyra’s path for vengeance, and the further Cyra descends into the deadly world of serial killers, the harder it becomes to hold on to her own humanity. 

This dark, witty debut novel is a cunning homage to women’s wrongs that will have you wondering exactly how many monsters walk unseen among us.
