Step Sister Stories Novels & Stories

My father called me to his study to deliver an order. I, Victoria Castellano, was to take my illegitimate half-sister Isabella’s place, to marry the comatose heir of the rival Moretti family and secure a truce. I didn’t cry. I laid my kid gloves on his polished desk and made my three demands. Sever all ties. My mother’s entire legacy. And give my bodyguard, Nicholas, to Isabella. Everyone knew my obsession with him. I loved him until I overheard the truth. He was the hidden Rossi heir, undercover only to protect his precious Isabella. Every time he’d saved my life, he was just guarding his link to her.

And I’ll never tell him that three years ago, in Lake Tahoe’s freezing depths, the lips that breathed life back into a drowning man—the memory that haunts him—weren’t Isabella’s. They were mine.

I personally selected that scholarship from over a dozen institutions. How did it become her niece's? Seeing Harper's face turn purple as she falls unconscious, I demand they bring her down. The woman throws a 100-thousand-dollar check at me and says, "I'd like to see who dares to let her down. Take this money as payment for your sister's life. The three Simmons brothers are my sons. Not to mention the life of a nobody like her, even with you included, I can still afford it!" I am enraged! The three Simmons brothers are just poor students whose education I funded.

Despite dreaming of attending university all my life, I ended up stuck in my farming village. I married my brother-in-law and became my nephew’s stepmother. This all happened because my sister died trying to make money for my tuition fees on the day my results came out.
