The Agreement by Nora Ford

Can a billionaire tame a stunning, dark-haired beauty’s heart?
Aron is an arrogant, successful, and all-out sexy billionaire, with one little problem. If he doesn’t marry his deceased brother’s fiancée then he loses 30 percent of the company. Losing isn’t an option, it’s not even in Aron’s vocabulary.
Too bad for him Tessa doesn’t do relationships and she sure isn’t looking to start. So when she agrees to marry him it’s just that an agreement, not a relationship, no matter how much she starts to fall for him she won’t give in.
Can Aron show Tessa how to love again? Or will the both be burned by the past?
