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. She's committed both to taking her permanent vows with the Sisters of the Sublime Blood and joining 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 Mississippi river, and with it, Redemption's next case.

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 favourite punk nun-sleuth throws herself into the deep end yet again.
