Sorry, Mom. I Sold the Part of Me That Loved You

My family chose an orphan over me. My twin broke my body. My fiancé betrayed me. And my parents locked me away to die. So I sold my ability to love to a mysterious soul pawnshop for a second life. Now, I'm twelve again, and their precious new daughter has just arrived. This time, I won't beg to be loved. I'll walk away. But my indifference terrifies them, and one boy refuses to let me face this life alone. Why does he look at me like he's already lost me once? And what did my second chance cost?
