"We can't do this," I whispered, even as Jamie's fingers traced my jaw. "Tell me to stop," he commanded, his grey eyes darkening with desire. I should have. But instead: "I can't." His hand slid beneath my shirt. "This is wrong." "Then stop touching me." "I can't." His voice was raw. "Every night I think about you. About this."

Her back hit the cold wall before she could even breathe. Damian’s hand slid to her jaw, tilting her face up to his. His voice was a low, trembling threat. “Do you feel what you’re doing to me, Aria?” Her heartbeat stuttered. “You’re my sister’s husband…” “Exactly,” he whispered. “That’s why I shouldn’t want you.” He leaned closer, his breath brushing her lips. “But wanting you is all I’ve done… every damn day.” *** Aria Hale has spent her life unseen, ignored by her father, used by her sister, and taught that her feelings don’t matter.

In the Valenti Family, you're born with a chip. It's fused into the bio-watch on your wrist, its digital face counting down every second you have left to live. Everyone could see the numbers ticking down on my twin sister's watch. And on mine. They all knew she would die on our 18th birthday. So Vivian became the untouchable princess of our brutal world. Every diamond-stitched gown was hers. The rarest jewels were hers. Even our father's last shred of humanity was hers. That single sliver of warmth he showed only after his gun was holstered. I used to pity her. Her time was running out. But God, I envied her. She had everything I never did: our parents' love. Then, the night of her 18th birthday party. My parents worried I'd make a scene. That I'd piss off the Don of an allied Family. So they locked me in the cellar. Damp. Cold. While a deadly fever burned through me. I pounded on the heavy oak door, my voice cracking. "Mamma, please! Let me out! I'm burning up. My head is splitting open…" Outside, my mother's voice was a steel trap. "Enough, Sienna! Today is your sister’s 18th birthday. Her last day alive! Stop the theatrics! Can't you suffer in silence for the Family's honor?" "But I'm really sick..." Her footsteps clicked away, fading into nothing. Then the darkness swallowed me whole. And on my wrist, the bio-watch was flashing a critical alert. CRITICAL ALERT: Vital signs mismatch. Paired chip data incompatible. Please verify user.

"Congratulations. Maybe you can keep my husband too?" My husband's reaction? He blew up and dismissed me. "I just donated my seed to Cara! Don't make a scene, Barb!" Oh, I'll make a scene.
