Raegan McGovern is the most powerful witch born to the Prestwick Coven in the Highlands of Scotland. Her awakening heralds the choice she must make, to be a member of the Dark Ones or an Ethereal the same as her mother. Before her awakening can happen, she is whisked away to Rome for an audience with the Guild, a collective of powerful paranormals who may not have her best interest at heart during a time when being a witch is punishable by death. The Sentinel charged with protecting her, Marcus Langlier, is her only hope at surviving. Can he make the right choice and prevent Raegan from embracing the Dark Ones when she is the strongest witch ever born to the witches of Prestwick? Or will her rage overshadow the goodness Marcus has seen in her heart?
