Sister Holiday is back with a newly minted PI apprentice certificate, a twisty mystery to solve, and something to prove in this fast-paced, blistering follow-up to Scorched Grace. Tattooed from her neck to her toes and sporting a gold tooth as sharp as her wisecracks, Sister Holiday struggles to stay on the righteous path. Never one to make things easy for herself, she’s committed to taking her permanent vows with the Sisters of the Sublime Blood and joining former fire inspector Magnolia Riveaux’s latest venture, Redemption Detective Agency―both in service of satisfying her eternal quest for answers. When Sister Holiday and Riveaux set out to bust a philandering husband, they instead find the body of a priest floating in the swollen Mississippi River, and with it, Redemption’s next case. It’s significantly more gruesome than their orig­inal mission, but Sister Holiday feels called on by God to hunt down the murderer and keep her community safe. As a torrential rainstorm drowns New Orleans for three harrowing days over Easter weekend, Sister Holiday and Riveaux follow the clues. With the stakes rising alongside the relentless floodwaters, our favorite punk nun-sleuth throws herself into the deep end yet again. A lacerating and lyrical plunge into obsession, deception, and the questions that hold us captive, Blessed Water is a lights-out mystery that will leave you breathless.

Sister Holiday, a chain-smoking, heavily tattooed, queer nun, puts her amateur sleuthing skills to the test in this debut crime novel. When Saint Sebastian's School becomes the target of a shocking arson spree, the Sisters of the Sublime Blood and their surrounding community are thrust into chaos. Unsatisfied with the officials' response, sardonic and headstrong Sister Holiday becomes determined to unveil the mysterious attacker herself and return her home and sanctuary to its former peace. Her investigation leads down a twisty path of suspicion and secrets in the sticky, oppressive New Orleans heat, turning her against colleagues, students, and even fellow Sisters along the way. Sister Holiday is more faithful than most, but she's no saint. To piece together the clues of this high-stakes mystery, she must first reckon with the sins of her checkered past-and neither task will be easy. An exciting start to Margot Douaihy's bold series for Gillian Flynn Books that breathes new life into the hard-boiled genre, Scorched Grace is a fast-paced and punchy whodunnit that will keep readers guessing until the very end.
