Ashton/Rosemoor (#0.5)
He's notorious for his wicked ways...

Frederick Stoneham thoroughly enjoys the life he leads as one of London's most disreputable rogues. When his father arranges for him to wed Lady Eleanor Ashton, he believes his decadent lifestyle can carry on uninterrupted. After all, he remembers Eleanor to be plain and timid—not the kind of wife who will demand attention or insist he leave his mistress. But Frederick has a change of heart when he sees the striking beauty Eleanor has become.

Can she reform him?

Eleanor is stunned to discover she is to wed Frederick Stoneham—the man she has secretly pined after for years, despite his reputation. When Frederick's former mistress tells her a horrible lie, Eleanor feels betrayed. But Frederick's persistence—and a passion that refuses to be ignored—are slowly melting Eleanor's resolve. Now Frederick must prove to Eleanor that his days as a rake are in the past and that she is the only woman he will ever love.
