The Mistress Affair — Kate Silver

Kate's young son needs an expensive operation or he will die. Her last hope lies in borrowing the money from Alex Gattung, a business tycoon and distant relative. He thinks she is a gambler down on her luck and offers her a devil's bargain - sleep with him, and he will loan her the money she needs. Her desperation forces her to agree to his terms. But what neither of them counted on was falling in love.
