Nicolas Deschanel spent thirty-two years holding court as the princeling of New Orleans and heir to his family's dynasty, with no obligations beyond his own pleasures. Following a storm of events, his rock bottom leads him back to his family, where he finds redemption in contrite service. Paired with the pragmatic Lauren-who is deeply skeptical of his reformation-the two spend their days in seclusion, cultivating the lofty research goals of the Deschanel Magi Collective. Charlotte Fontenot is calculated and driven in her approach to her mission in Paris. With help from her cousin Julian, they follow Gabrielle and Lawrence Henry, siblings whose unusual behavior has caught the attention of witches in Paris. The cousins quickly realize neither sibling is what they seem, and Charlotte's fearlessness leads her closer and closer to mysterious philanthropist Lawrence. With Charlotte and Julian settled in Paris, Nicolas and Lauren shift their focus to a special, secret project: quietly and carefully investigating the women of the powerful LaViolette family, distant cousins of the Deschanels. This assignment quickly leads them down a dangerous path, one where turning back is no longer an option. Events in both New Orleans and Paris begin to spin wildly beyond the control of all involved, and when the dust settles, nothing will ever be the same.
