Blind Faith by Diane and Jacob Anderson Minshall

In the detective business, the ordinary can quickly become deadly. When private investigator Yoshi Yakamota and the Blind Eye Detective Agency are hired to find a woman’s missing sister, the assignment seems fairly mundane. Then two teens fall to their death from a rocky oceanside cliff in what appears to be a tragic accident. Although the events seem unrelated, they have one thing in common: the controversial Pioneer Institute, a residential ex-gay youth program. Will sending a Blind Eye team member undercover reveal what's behind the school's terrible safety record, or will it just put the spy in harm’s way?
