Seducing the Billionaire Stepmother

My name is Fina. After growing up in an orphanage for 20 years, I discovered I’m the true heiress of the top-tier wealthy Castle family. ​ However, my first day home was a nightmare. I caught the fake heiress, Evelyn, hooking up with my eldest brother, Theodore. To keep me quiet, they shoved me onto broken glass and forced me to marry Austin, a mafia heir, in Evelyn's place. ​ Heartbroken, I went to a bar to get drunk and met an elegant short-haired woman who rescued me from being harassed. Intoxicated, I kissed her, and we shared a wild one-night stand. ​ At the family banquet the next day, Evelyn framed me for stealing a billion-dollar sapphire necklace. As everyone humiliated me, my savior from last night appeared—only for me to realize she was Helena, my stepmother and the ultimate boss who controls the entire Castle family. ​ Instead of exposing our night together, Helena protected me while secretly seducing me. I kept trying to run away from her, until I caught my so-called fiancé Austin making a move on Evelyn. Devastated, I finally gave in and fell into Helena's arms. ​ In the hallway outside Theodore's room, under the banquet table, and in her office... we crossed the line over and over again. The intoxicating thrill of this taboo romance completely destroyed all my defenses.​
