The Highland Earl's Revenge. Highland Lords and Ladies

Lady Arabella Fraser will do anything to protect her clan, even if it pits her against the man she loves and the army of the English king Scotland 1744-1746At sixteen, Lady Arabella Fraser, is forced into marriage with seventy-year-old, Lord William Gordon. Her father, Lord Fraser, insists the union will bring him and the Gordon lord a dukedom from Bonnie Prince Charles, and free the Highlands from the scourge of English rule.
In desperation, she throws herself at the man she loves, young disposed noble, Alexander Gordon, and begs him to marry her, greatly humiliated when he refuses. Two years later, unhappily married, Arabella swears she'll never forgive Alexander for leaving her and joining the enemy army to fight under King George instead of marrying her. The day after the Scottish defeat at Culloden Field, Captain Alexander appears in Gordon castle at the head of the English army to wreak havoc on all traitors to the throne.
Alexander cannot forget that Arabella wouldn't wait for him and married his uncle for the wealth, title and castle, that should have been his. Except he still loves her and wants to make her his.
