Desperate Single Mom to Business Queen

The prenatal appointment had gone wonderfully. Dr. Martinez assured me that Hope was developing perfectly, her heartbeat strong and steady. I pressed my hand to my rounded belly as I drove home, imagining Ethan's face when I told him we'd finally settled on the name. Hope Thorne Vance. It felt right, like a promise of the beautiful future we were building together.

I'd stopped at the market to pick up ingredients for his favorite meal—braised short ribs with roasted vegetables, the dish that had won him over during our college days when I'd cooked for him in my tiny dorm kitchen. The memory made me smile as I fumbled with my keys at the front door, grocery bags weighing down my arms.

The house felt unusually quiet as I stepped inside. Ethan's car was in the driveway, but he hadn't called out his usual greeting. Maybe he was taking a nap—he'd been working such long hours at Daddy's company lately, staying late to prove himself worthy of the promotion we both knew was coming.

I set the groceries on the kitchen counter and kicked off my heels, my swollen feet grateful for the relief. The baby shifted inside me, and I rubbed the spot where her tiny foot pressed against my ribs.

"Ethan?" I called softly, not wanting to wake him if he was resting.

The bedroom door was slightly ajar.

I approached slowly, my bare feet silent on the hardwood floor. The sounds grew clearer—breathing, movement, whispered words I couldn't quite make out. My hand trembled as I reached for the door handle.

I pushed it open.

The world tilted.

Ethan was there, in our bed, his body moving rhythmically above someone else. Someone with long, dark hair spread across my pillow. Someone whose face turned toward me at that exact moment, eyes meeting mine with a shock that quickly transformed into something else entirely.

Isabella.

My stepsister smiled.

A scream tore from my throat, raw and primal. "What the hell is this?"

Ethan jerked away, his face flushed with exertion and shock. "Amelia! You're supposed to be at your appointment—"

"Get off her!" I shrieked, my voice cracking. "Get off my sister!"

But Isabella didn't scramble to cover herself. Instead, she stretched languidly, like a cat in the sun, making no effort to hide her naked body. "Hello, Amelia. You're home early."

The casual tone, the
