First, do no harm. But as New Orleans PI Micky Knight discovers, not every health care provider follows that dictum. She stumbles into a tangle of the true believers to the criminally callous, who use the suffering of others for their twisted ends. In a city slowly rebuilding after Katrina, one of the most devastated areas is health care, and the gaps in service are wide enough for the snake oil salesmen—and the snakes themselves—to crawl through. First, her investigation is driven by anger, but then it becomes personal as someone very close to Micky uses her cancer diagnosis to go where Micky cannot, into the heart of the evil where only the ill are allowed. Micky is her only lifeline out. Can Micky save her in time to get to the medical treatment she desperately needs to survive? The seventh Micky Knight mystery.
