It's a steamy, restless end of the school year in New Orleans. Sister Holiday is finishing her music classes and preparing for her permanent vow ceremony, a pivotal moment in her journey of faith. But when one of her favorite students is found dead of a fentanyl overdose, Sister Holiday and her partner-in-PI, Magnolia Riveaux, are determined to track down the drug dealers. As students continue to fall prey tothis sinister drug, Sister Holiday becomes more desperate to stop the epidemic--while facing her own past with addiction, a demon that is never too far.

With Douaihy's signature mix of grit, heart, and faith, Divine Ruin tests the limits of Sister Holiday's devotion in her darkest and most shocking case yet.
