How the Wallflower Wins a Duke

Marina Fletcher's Rules:

Rule 1: Spend life composing music in peace. Do not worry about finding a husband.

Rule 2: If must worry about finding a husband, marry for love only or commit to becoming a spinster.

Rule 3: Resist urge to spend time with the sinfully sexy Duke of Framlingham, who clearly does not believe in love.

Rule 4: Never ever say yes to said duke's wicked plan for us to silence society's expectations with a fake engagement...

But what happens when this wallflower breaks every single rule?
