The Lord's Scandalous Mistress (The Oxford Set #2)
Ava Bond

Lord Nicholas Lynde has always enjoyed a carefree life as a young bachelor, deliberately avoiding all things scandalous. When he returns home to find a marauding gang of thieves on his father’s land, he must act swiftly, regardless of the danger.
But he didn’t expect one of the smugglers to be a beautiful, spirited young widow who makes him question all of his rules. A battle of wills begins, with neither fully trusting the other, but ever so tempted to. Will Isabel and Nicholas find an ally in each other, or maybe something better?
