"Years after her son's fatal overdose, grieving mother Rachel Higgins learns that his addiction may have grown out of damage suffered at the hands of a pedophile priest while he was in high school. Looking for vengeance, she targets the Catholic Church's most visible local figure, Archbishop Francis Gillespie. When the archbishop begins receiving anonymous threats, local police dismiss them, saying they're not credible. So he turns to his friends, Ali Reynolds and her husband, B. Simpson. With B. out of the country on a cybersecurity emergency, it's up to Ali to track down the source of the threats. When a shooter assassinates the archbishop's driver and leaves the priest himself severely injured, Ali forms an uneasy alliance with a Phoenix homicide cop in hopes of preventing another attack. But Ali doesn't realize that the killer has become not only more unhinged but also more determined to take out his or her target." -- Provided by publisher.
