Isabella Sinclair, a thirty-two-year-old billionaire heiress, dislikes men and never intended to get married. However, her convictions were put to the test when she had a one-night stand affair with a strange guy, Liam Blackwood. ********** Liam grabbed her wrist tightly and in a swift movement, he lifted her and dropped her on the bed. He pinned her hands on the bed with one hand, while the other hand slowly caressed her lower abdomen. A sudden gasp escaped Isabella’s lips as his gentle touch landed on her lower abdomen. He leaned into her and moved his lips near her ear. She flinched in fear. ‘Are you going to bite me like I did? Don’t be petty!’ she snapped sharply as Liam’s lips grazed her earlobe, his breath fanning against her skin. He chuckled slightly at Isabella’s outburst, and in an unexpected move, he flickered his tongue into her ear. She froze! She liked it and wanted him to do it again, but instead, he whispered, ‘Young lady, have you forgotten? No contact! Why do you keep throwing yourself at me, little girl!’ “What! ‘Little girl’? How dare he!” she screamed in her head, but in reality, she liked how possessive and dominant Liam is. He freed her, releasing his tight grip on her hands and jumped off the bed. He grabbed his car keys from the bedside table and walked towards the door. “Liam! The contract! Do you want me to change it? And by the way, this is your second night here, and you haven’t given me a foot massage yet,” Isabella called out as he placed his hands on the doorknob.

“We’re friends,” I said, voice barely steady. Aaron’s lips curled, slow and cruel. “No, we’re not.” “Friendship’s too pure for this.” His hand slid to my waist, hot and claiming as he yanked me flush against him. “Do friends kiss like this?” He kissed me. Hard. Possessive. “Or grab each other like this?” A squeeze to my ass. A gasp. “Or think filthy little thoughts?” His breath burned against my ear. “Touch themselves to it?” My cheeks flamed. My body betrayed me. “Stop lying, Venus.” His voice was a growl. “I feel it. Every time I’m near you.” I whispered, “But you don’t even like me.” His smile was pure sin. “I don’t have to like you to fuck you.” Then the offer: “Let’s get it out of our system. No lies. No strings. Just truth.” He grabbed my chin, eyes lit with hunger. “Say the word, princess.” A whisper against my lips— “I’ll ruin you.” And God help me… I wanted him to. --------- Aaron Sinclair needs a bride to claim his inheritance.

I was diagnosed with Wolf-Soul Decay Syndrome on my birthday, which meant I was on the verge of death. But my older brother, Alaric Sinclair, bought the only tube of Moonviolet serum—a serum capable of saving my life—just so he could give it to my younger adopted sister, Megan Sinclair. He thought I faked my illness in order to attract everyone's attention. Because of that, I stole the serum when no one was looking and took it. That night, Megan drove away from home in tears, only to be met with a fatal car accident that took her life. I was cast out of my childhood home by my parents.

When I mention that I can give away my spot at the marking ceremony, Kenneth praises me for being an understanding fiancee. When I hand over my design company, which is in the top 500 rank, to Megan, my parents are satisfied with me. "You've finally learned how to be selfless, Evie," they say. But Alaric grabs my hand and roars, "Didn't you claim that you'd never give those things away unless you die? Why are you giving them away now?" That's because I'm about to die, dear brother.
