His Regret, Her Redemption.

“Catherine (Cat) Landon thought she had built a life of trust and love with her husband, Alex Dawson-until she discovered he had emptied their savings to buy a diamond ring for his mistress. Heartbroken and lost, she sought escape in a club, only to be mistaken for a stripper and paid for a one-night stand by a mysterious stranger. That stranger was Aaron Dawson-her ex-husband's ruthless older brother. Moments later, Cat finds herself at the mercy of a contract marriage with the same man she spent one unforgettable night with. Aaron is cold, calculating, and holds secrets of his own. He doesn't believe in love, but he refuses to let Cat walk away. As she's pulled into Aaron's world of wealth, power, and deep-seated family betrayal, Cat must fight to reclaim her identity and seek revenge on the man who wronged her. But Aaron's presence stirs something dangerous inside her-a passion she never expected. When old wounds resurface and dark secrets unravel, Cat must decide: will she allow herself to be consumed by vengeance, or will she open her heart to a second chance at love?”
