Matty has lost his soul, and it's up to Frankie to find it before his body gives up the fight for survival. But soon his isn't the only life at risk from the soulless condition. The affliction is spreading from Thunderbolt, Georgia, into the beating heart of the French Quarter and right up to Madam Vionette Fontenot's front door.
When Frankie returns to New Orleans in search of answers, she finds herself at the mercy of a god who covets her newfound powers as the guardian of the Alcheyvāhā. He makes it clear he's willing to do whatever it takes to wield her for his own benefit. Even if it costs Frankie everyone she loves.
