The supernatural war is heating up in New Orleans. Just days after helping put down a coup to overthrow the city's vampire leadership, Juliette de Grammont—voodoo priestess and magic-using vampire—is summoned to the scene of a grizzly double ritual murder. There is a dangerous new supernatural enemy targeting vampires and their human lovers to reap their souls. As Juliette races to discover the identity of the necromancer, she is forced to recon with her own weaknesses and an ever increasing body count.

Working with the local werewolf pack and the Gatekeepers—a shadowy group of mages dedicated to keeping the paranormal world secret from humans—Juliette seeks to keep New Orleans safe for all who dwell within its borders.
