Serial killer support group : a novel (engelsk)

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.
