When Forensic Investigator Lilith Adams accepted Detective Andrew Cohen's help to defeat the horror from her father's past, she knew she was making a deal with the devil. Now the true price has come to light, and the cost is beyond anything she imagined. Lilith and Chance are forced into the service of a mysterious council, whose brutality rivals Ashcroft's in their rabid desire for the Voynich manuscript and its cipher.

Every loyalty and shred of sanity are utilized as opposing factions desperately race for the power hidden within the enigmatic book, which recently went missing in a high-tech robbery at the Beinecke Library in New Haven, Connecticut. Now Lilith, Chance, and Cohen are tasked with finding the book, which holds the ghosts of Gregor's past and a mysterious connection to the Durand. Caught between emotion-feeding demons, a vicious siren, and an actual voodoo witch with terrifying power, the real question is, who will be left standing when the storm passes?
