Deal With The Devil - Married At Midnight, #1

I'm the potential heir to a billionaire's fortune. The only problem? My grandfather demands that the winner be married. I don't believe in any of that romantic claptrap. But I admit that I need a wife and a baby to wrest control of the family company. That's where pretty little Talia comes in.  My brother Burn stole my fiancée and plans to ruin my shot at the fortune in question. But when a lovely young Talia slaps me, calls me Burn, and says she is pregnant.
It takes me a second to work out that Burn has knocked her up. And then the pieces fall together perfectly. A plan to control the empire and spoil Burn's engagement in one fell swoop. I offer Talia a devil's deal. Play my doting wife. Pretend her baby is mine. Smile and fake it in front of the family, despite the fact that she seems to hate me. Rub her happiness about the sham marriage in Burn's face. As a reward, Talia will have more money than she could ever even dream of.
Diamonds will drip from her neck. Gold will adorn her wrists. Cold hard cash will keep her warm at night for the rest of her life. Her baby will have only the finest things and my last name as shelter. I won't take no for an answer. All Talia has to do is say yes. till death do we part.
