The Secret Fiancée: Lexington and Raya's Story by Catharina Maura

The story follows Raya, a woman who believes she is navigating a completely normal life, unaware that her future has actually been dictated by a long-standing family arrangement. Because of an old pact, she is contractually betrothed to Lexington Windsor, a powerful, cold-hearted billionaire and the next in line to lead the massive Windsor empire.

Wanting to understand the woman he is legally bound to marry without the pressure of his family name, Lexington chooses to approach her in secret, hiding his true identity. Posing as an ordinary man, he infiltrates her world to see who she really is. What starts as an observation quickly spirals out of control as real feelings develop, leaving Lexington trapped in a web of his own lies while Raya falls for a version of him that isn't entirely real.
