Married to My Sister's Lover

For five years, I was nothing more than my sister's stand-in. In our marriage bed, he whispered her name, not mine. When his true love—my sister—fell gravely ill, he didn't hesitate. He forced me onto the operating table and took my kidney to save her life. Lying broken in a hospital bed, I learned the final, soul-crushing truth: he was also responsible for my grandfather's death, the only family I had left. My heart turned to ash. He tossed divorce papers at me, thinking it was over. But fate had one last cruel twist in store. I'm pregnant.
