Rich As Sin Books in Order

Rich As Sin is a dark billionaire trilogy written with Kristen Luciani, and it stays close to one central couple as the danger keeps climbing. The setup is pure high-stakes romantic suspense. Lincoln Theroux is a powerful man living on revenge after the death of his wife. Bella, who is also pulled into the story under the name Rose, steps into his path at exactly the wrong time. What should have been a clean hit in a club turns into a much messier game of desire, mob violence, and divided loyalties.

That one mistake powers the whole trilogy. Lincoln is not a hero who strolls in ready for love. He is cold, watchful, and committed to destroying the man he blames for ruining his life. Bella is not just scenery in his revenge plot, either. As the books move from His Dark Obsession to Her Dark Vengeance and Their Dark Empire, she has to decide how much of herself she is willing to lose, and how far she will go to survive a world that keeps trying to use her.

Expect nightclubs, penthouses, criminal families, private deals, and a romance that grows in the middle of constant pressure. The tone is dark, possessive, and suspense-heavy. This series is best for readers who like one-couple trilogies, cliffhangers, and relationships built under stress rather than comfort.
