The line

Savannah looks like any other graceful Southern city on the surface, but those who look closer find a hidden community where witchcraft is accepted, Hoodoo inspires fear, and the dead do not always stay gone. Mercy Taylor knows this world well. She belongs to the most influential witch family in the American South, though she has no magic of her own.

Mercy has spent her life living in the shadow of her gifted, magnetic twin sister, and she has largely accepted her place. A chain of misfortunes, ending with the death of the Taylor family matriarch, disrupts the spiritual foundations that hold Savannah's supernatural order together. Mercy is drawn into a mystery that threatens to tear her family apart.

The unraveling mystery also threatens to free a darkness that generations of Taylor witches have kept contained.
