While on her second honeymoon in the British Isles, Claire touches a boulder that hurls her back in time to the forbidden Castle Leoch with the MacKenzie clan. Not understanding the forces that brought her there, she becomes ensnared in life-threatening situations with a Scots warrior named James Fraser.
