My Sister Keeper

I would like to start off first by saying a few word's about myself. My name is Brooklyn Hemlock I am seventeen years old oh and I'm dead. Yes dead? as in I am one of the under dead a lost soul you could say. How did I die you ask? well I don't know, I don't remember how. I do know that it was murder it was plan meaning someone killed me. Who? well I don't know that either that's where my twin sister Alexia comes in. I didn't know I had a twin sister my parents never told me. I had found out just a few weeks before my death.
