Blessed Water by Margot Douaihy

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.

"Sister Holiday is simply a joy of a narrator-and definitely my kind of character: flawed, dark, buoyant, and often laugh-out-loud funny." -Gillian Flynn, Gillian Flynn Books
Tattooed from her neck to her toesand 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.
