After inheriting the title and family estate in Devon Foxworth Morgan plans to go there, but instead heads for Scotland. He suffers from nightmares and guilt over the battle of Culloden. Being on the battlefield brings him no peace, yet he still stands there as a storm rolls in off the bay and he is struck by lightening. Grace MacClellan is walking on the moor trying to dissuade her friend Alex MacDonald’s from proposing marriage when she comes upon a man, scorched, but alive. She insists upon taking him to her castle Glenraven to be nursed by her sister –in- law, Maude. This angers Alex, especially since he must leave the next day for Edinburgh to join the Scottish Parliament. These are troubling times for Scotland with the British using economic pressure to force a union, a move some Scots applaud, but many resist. When Fox discovers the date, over forty years earlier than when he was struck by lightening, he at first thinks he is going mad, then slowly begins to accept that he has traveled through time.
Fox and Grace have an immediate attraction and she believes Fox when he tells her of the troubles that will befall Scotland. A patriot, Grace decides she must do what she can to change history. She convinces Fox that he was sent back in time to change what he knows will happen. He is anxious to get Grace away from Glenraven after a second attempt is made on her life. Grace is a widow whose husband killed himself after the Darian Project, an enterprise he backed, failed, and he was accused of profiting from the debacle. Grace was implicated as well. When they stop at the castle of a supporter of Grace and her husband, Fox recognizes Lord Archey’s soul as that of evil from his other life. Fox and Grace’s love for each other deepens and they decide when their work is completed they will return to Glenraven and marry. They realize they cannot stop the union of England and Scotland, but perhaps they can pull all the sides together and have them work toward what’s best for Scotland. They manage to convince the English and Royalists, the Jacabites, and the moderates to meet. The place chosen for the meeting is Lord Archey’s castle. Since Fox thinks Lord Archey responsible for the attempts on Grace’s life, he tries to convince her not to go, but she is adamant. The day after the talks commence Grace rises early and confronts Lord Archey in his rose garden. She accuses him of trying to kill her and planting evidence that she and her husband profited from the failure of the Darian Project. He knocks her out and locks her in a small, secluded shed on his estate. When Fox discovers Grace gone he accosts Lord Archey, and is banned from the estate. He returns and discovers the shed, but Lord Archey has already gone back for Grace and she has killed him with a pitchfork after he admits to killing her husband. The talks dissolve, and Fox and Grace realize there is nothing they can do to change history. What will happen; will happen. But they have found one another. They set off for Glenraven, anxious to get on with their lives. As they near Glenraven a storm rolls in off the bay, Grace rides toward Glenraven, her horse stumbles and she is killed. Cursing fate, Fox stands on the moor and is hit by lightening. Mary MacClure and her father are traveling through Scotland spreading word about their colony in the Carolinas. The year is 1748. As Mary walks along the moor near Culloden she stumbles upon a man, charred, but not dead. Fox Morgan awakes to find the love that has lasted through time.
