Claimed by My Fiancé's Uncle

My fiancé cheated with my sister. So I slept with his uncle. Cassian Blackwood is my boss's boss, the most powerful man in the city, and absolutely off-limits. One night was just payback. Then he made me Head of Acquisitions. Then he bid five million dollars on a pink diamond for me. Then he told his father he'd rather die than lose me. But Cassian already has a fiancée—American royalty. And his father has a message for me: disappear, or disappear permanently. They think I'm a nobody they can crush. They don't know I'm carrying the heir to both empires. Revenge got me into this. Love is going to get me out.
