I Switched Lives With My Twin Sister To Take Revenge On Her Stepmother

My name is Linda. I’m 17 years old. My parents adopted me when I was a baby. I grew up in a warm, loving home, getting everything I needed. They never made me feel like I was adopted. I was never curious about my biological mother and father. I wonder if I had searched for them, would I have found out that I had a twin sister..?
