SOME HEIRS ARE HIDDEN.
SOME BLOODLINES ARE STOLEN.
AND SOME NAMES SHOULD NEVER
BE WRITTEN BACK INTO THE WORLD.

Reagan Vale is still learning what it means to be the Blood Archivist of Mercy Row—a witch bound to an ancient Archive that records the bloodlines of vampires, werewolves, fae, witches, and every other hidden creature living in the shadows of the human world.

When a terrified girl with no true name appears on Reagan’s doorstep, she brings the Archive its first petition: a claim of stolen blood, false inheritance, and a death that should have stayed buried.

The powerful House of Arden insists the child belongs to them. But the girl remembers drowning in the Black Lily Pond twenty years ago, and the records Reagan uncovers suggest someone altered the truth, buried a murder, and rewrote an entire bloodline.

With vampire Nikolai Veyne as a reluctant witness, werewolf Callum Thorne following the scent of broken blood, and fae Grania Ashbriar guarding secrets of her own, Reagan must untangle a case that reaches far beyond one missing heir.

Because the girl may not be who Arden claims she is.

And beneath the black lilies, something older than blood is waiting to be found.
