Poppy Sinclair Novels & Stories

I was the real daughter of the Sinclair family, yet I was the one abandoned when their fake daughter and I were kidnapped and taken to the top of a building. They were given a choice between the two of us, and they chose to save the fake daughter, letting me be pushed off from the eighteenth-floor balcony. Even though I survived, I was completely disappointed in them. Then, their attitudes changed overnight. My parents, who despised me, started asking me about my likes and dislikes. My brother who wished me dead, started suddenly giving me precious jewelry. Even my fiancé, who always claimed I was nothing compared to the fake daughter, started to prepare for our wedding. To say I was confused was an understatement.

The day my husband, Lucas Maxwell, helps his childhood sweetheart—Cecilia Brown, who has cancer—lose her virginity, I leave behind a divorce agreement and walk away. Before I leave, I drop a comment beneath a photo of them on his social media. Their fingers are tightly interlocked in the photo. "Let's get divorced. I wish you both a lifetime of happiness." A minute later, he calls me. "How did I end up marrying someone as selfish as you, Fiona Sinclair? Do you really have the heart to let her die without leaving anything behind?" I sneer, "You're no longer my husband. How is that my problem?" That's when he panics.

"My engagement party is tomorrow," Cecilia said calmly. "But I'm missing one thing." "What?" he asked. She smiled. "A fiancé." "My pleasure," he said, voice low and steady. "Miss Fiancée." *** The night before her engagement party, Cecilia is betrayed by her ex and her own cousin. But humiliation won't be her ending. In a bold move, she picks a devastatingly handsome stranger to play the role of her fiancé. What she doesn't know is--Liam Sinclair isn't someone you simply "choose." He's dangerous, powerful, and far from ordinary. By the time Cecilia realizes who he really is, it's already too late. Because Liam never lets go of what's his.
