The Duke of Desire: The Untouchables, Book 5 (Unabridged‪)‬

Ten years ago, Ivy Breckenridge's life was ruined. She had to reinvent herself, and now, after painstakingly making her own way in the world, she's nearly forgotten the dreams of home and family she'd once nurtured. Until one man peers into her soul and awakens every one of her hidden desires. But no matter how good he makes her feel, she can't trust him - alone by choice is better than alone by necessity. 

With a notorious reputation for training married women in the art of passion, Sebastian Westgate, Duke of Clare, is reviled by some and celebrated by others. He doesn't allow anyone close enough to see past his charming exterior. When Ivy uncovers the man beneath, the seducer is suddenly the seduced. Enraptured by her mind and spirit, he wants more but revealing his darkest secrets is a price he won't pay.
