The Harper witches have grown apart in the ten years since they defeated Toxanna and Will Brown. Each of them are on their own missions in the magical and the non-magical worlds. However, one by one, the witches are warned of a powerful force that has been unleashed that may also be linked to the death of Chris and Holly’s baby daughter. As they fight for answers to this new threat on their own, they soon discover that they have no other options but to ask for help. Unfortunately, family isn’t always the first choice for sanctuary.
