On her way to a reenactment of a medieval festival in Scotland, Amber McPhee loses control of her car. She plunges into the waters of Loch Ness and back through centuries to the arms of a handsome Highlander.
The immortal warrior Lachlan MacAlpin rescues a mysterious woman from Loch Ness, believing she is the one who haunts his dreams, the one foretold to release him from the bloodlust that threatens to consume him. He takes her under his protection, but falling in love with her is not part of his plan, since the prophecy predicts she will leave him as suddenly as she appeared.
Their eternal bond shatters the barriers of time, but how can they triumph over a deadly foe bent on destroying their love and everything Lachlan holds dear?
