Some families pass down heirlooms.

The Vales passed down secrets.

When genealogist Reagan Vale inherits her estranged grandmother’s house on Mercy Row, she expects legal paperwork, dusty records, and difficult memories. Instead, she discovers a hidden archive that tracks bloodlines stretching far beyond the human world.

As names begin disappearing from history itself, Reagan finds herself hunted by witches, watched by ancient powers, and drawn toward Nikolai Veyne—a vampire whose own lineage is unraveling.

The deeper she digs, the more impossible the truth becomes.

Because the archive was waiting for her.

And so was the blood that built it.
