War is coming to Mercy Row.

As Blood Archivist Reagan Vale struggles to hold together a world built on dangerous bloodlines, old loyalties begin to fracture and ancient enemies step out of the dark. When a gathering of powerful supernatural houses ends in suspicion, betrayal, and death, Mercy Row becomes the center of a coming war.

With the Archive under threat and the hidden world closing in, Reagan must rely on vampire Nikolai Veyne, werewolf Callum Thorne, and fae noble Grania Ashbriar as she faces impossible choices that will test her power, her heart, and her right to lead.

Because some houses fall quietly.
Others take the world with them.
