I had stayed up for 3 nights straight preparing for my wedding to Julian Cross. I had only just lain down when someone kicked open my bedroom door.   It was 3 a.m. My younger sister, Celeste Fletcher, stood there in a slip dress with a freshly opened bottle of champagne. Laughing, she flung herself onto my bed.   "Nadine, it's the bachelorette party! Why are you sleeping? Get up and have some fun!"   My head hurt so badly I thought it would split. "Celeste, I'm exhausted," I rasped. "Please let me sleep. The wedding's tomorrow."   My fiancé and my older brother, Marcus Fletcher, stood in the doorway.   "Nadine, you know how sensitive Celeste is," Marcus said coldly, his voice impatient. "Can't you give in to her for once? You're her older sister."   Julian frowned. "It's just one night. She wants to have fun. Keep her company."   They left me no choice. They dragged me to a bar for the party.   The next morning, I was late, just as I had feared. I barely had time to dress before racing to the wedding.   Julian stood there in the suit I had chosen, his arm linked lovingly with Celeste's.   When my father saw me frozen in the doorway, he strode over, his expression thunderous.   "You actually showed up dressed like that? Celeste told us you spent all night fooling around and couldn't even get out of bed this morning. Thank God she put on your wedding dress and stepped in. Otherwise, our family would have been a laughingstock!"   My mother stood protectively in front of Celeste, looking at me with disappointment.   "Nadine, how did I raise a daughter like you? You even slept through your own wedding."   I stared at the enormous wedding portrait of Julian and Celeste on the screen. Suddenly, I was so tired.   I couldn't keep trying to make this work on my own.
