She Falls by Winter Fox

They say that love conquers all. And I’m about to test that theory to its limit!

My name is Hayley Monroe, and I am an FBI agent—charged with bringing down one of the most infamous human trafficking organizations in the world.
A year of intensive training, inextricably bonds me to my handler—Ryan. But we both know that one day soon, he will have to give me up to one of the demon traffickers.
Being sold as a sex slave is the only way that I can infiltrate the demon’s dark world, and I’ve always known exactly what I’m letting myself in for.
But I didn’t bet on the oldest and darkest of all of the demon’s buying me, for the unheard-of sum of one million dollars.
Now I’m trapped in a world of lust, darkness and brutal conditioning. Trained to adore a monster who has hundreds of years’ experience in breaking down women’s defenses.
Ryan should be the only one who can bring me back from the brink of losing myself. But as the days pass by, and the lines begin to blur; I’m beginning to forget who Hayley Monroe ever was!
