She was looking for freedom....
When the always obedient Lady Iona is pressured into accepting a husband of her father's choosing, she seeks out the notorious rake, Lord Nathan Wynter, for his help in learning how to standup for herself.
He was looking for respect...
While Iona is seeking adventure, Lord Nathan is doing his honest best to reform his ways in order to repair his reputation and his disastrous relationship with his family. Winning the very proper Lady Iona for a wife would go a long way to achieving that end.
They found each other.
The more Nathan tries to protect Lady Iona from running head-long into disgrace, the more he admires her daring spirit and unpredictable antics. Instead of returning her to the obedient world to which she was raised, he encourages her blossoming passions. Such a move is surely going to lead them both to ruin.
But for love he is willing to risk everything.
