This sequel to Creatures of Will and Temper picks up in 1927 Long Island, where Ellie West fishes by day and sells moonshine by night to the citizens of her home town. But after Ellie’s father joins a church whose parishioners possess supernatural powers and a violent hatred for immigrants, Ellie finds she doesn’t know her beloved island, or her father, as well as she thought.

Amityville baywoman Ellie West fishes by day and bootlegs moonshine by night. It’s dangerous work under Prohibition—independent operators like her are despised by federal agents and mobsters alike—but Ellie’s brother was accepted to college and Ellie’s desperate to see him go. So desperate that when wealthy strangers ask her to procure libations for an extravagant party, Ellie sells them everything she has, including some booze she acquired under unusual circumstances.

What Ellie doesn’t know is that this booze is special. Distilled from foul mushrooms by a cult of diabolists, those who drink it see terrible things—like the destruction of Long Island in fire and flood. The cult is masquerading as a church promising salvation through temperance and a return to “the good old days,” so it’s hard for Ellie to take a stand against them, especially when her father joins, but Ellie loves Long Island, and she loves her family, and she’ll do whatever it takes to ensure neither is torn apart.
