Clan Hero. Highland Heroes, #4

With war devastating the landscape and Clan Creighton and Clan Buchanan at each other's throats, Dead Betty and Reid Buchanan get caught in a deadly race to track down the one man who can stop the war. No one can even find Duncan Buchanan, much less bring him to the throne to overthrow the deadly wizard Laird Balfour Creighton. Betty doesn't want to get stuck in this bizarre version of Scotland, especially not with a man as enticing and charismatic as Reid Buchanan, but the Fates conspire to throw a wrench in the words when Betty starts using magic she never knew she had.
When worlds collide, Betty will have no choice but to embrace every aspect of this new life, including her feelings for Reid that won't be denied. When the dust settles and the war finally ends, there may be nothing left, not even the man she loves.
