Erin is a young psychologist, with no time for anything but her work, and unable to remember anything about her past. She leads an uneventful life, but a lonely one, in which she secretly wishes for a soulmate... Conner is an unusual patient who approaches her, thrusting her into a strange world of darkness that runs beneath our own. He believes himself to be a creature of legend-a werewolf. But he also draws Erin with a roguish charm, and an irresistible feeling that seems to bind them together... Conner desperately tries to save her from an unknown evil that pursues her with a relentless passion that crosses centuries, an evil that once took her very soul away, somewhere in Erin's lost memories. As she becomes more entwined in a series of events that will remind her of who she really is, will she make it away from the oncoming darkness unscathed...?
