Imogen is a barkeep in a brothel to work off her dead father's debts. She isn't "for sale" until a wealthy Duke offers an extraordinary sum for one night with her before he goes off to fight in a major war.
Of course they share the best night of passion EVER, and he leaves her to her sad little life. She wore a wig and heavy eye makeup during their encounter, so when he returns years later on his deathbed after being a prisoner of war, he does not recognize the women tasked to nurse him back to health and treats her like garbage. He's kind of a jerk.
Besides being mistreated by her one time lover, Imogen also accidentally murders a man, and is offered a marriage of convenience to one of her elderly patients, which turns her suddenly into a titled lady and the next door neighbor of the Duke.
Cole (the Duke) only made it through his time as a prisoner due to his dreams of the woman from the brothel and is trying to find her. He still doesn't realize his new neighbor is the woman who haunts his dreams. In fact, he finds his neighbor irritating and tries to fight her wish to turn her home into a safe haven for women/children.

Interesting premise that I found a bit unbelievable, but well written and an enjoyable read. Characters from previous books by Byrne make an appearance, but you do not have to read them to enjoy this story.
