Savannah resident Mercy Taylor may now be in control of the South's most powerful family of witches, but she's struggling to master her newfound magic. Pregnant with her first child and still reeling from a heartbreaking betrayal, she just wants to be able to use her supernatural abilities without accidentally destroying dishes or blasting the doors off buildings. But when Mercy's long-presumed-dead mother suddenly returns, begging Mercy to keep her presence under wraps, the witch wonders how many secrets her family is hiding and who she can really trust. And when the danger around her intensifies to deadly levels, Mercy knows she must discover the truth behind her family's magic before it destroys her.
