Where is everyone going? Am I next?

Chapter 1: Here's what is happening

Hello my name is Lizzie. I live in different world than the one you are reading from. I live in a world where you need to prove your magic is good or you will "disappear". As a child I was in the attic of our old home I came across a minor that was cover in a heavy blanket that was once white now turned yellow. Though it took me a while I pulled the blanket off the minor only to be sucked into it to a place I don't understand. It was dark and creepy danger lurked every where. All I  wanted was to go home and I said those words the mirror appeared happily I ended up back home. My happiness was short lived after I came home I ran down the stairs to tell mom and  dad what had happened. But only mom stood there. I looked at my mother saying "Mother where's dad"?? My mother cried like I never seen her cry before all she said was "Gone he's gone to". This made wonder he's gone to? Who else was missing?? Today now 17  back then 6 I dared to climb back up there I was going to do it. Somehow the door was slammed tightly shut and nailed up. I said to myself "I don't remember that when this happen?" I wanted to ask my mother but she was out to the store. I did however find a letter in my grandmother's hand writing which was weird I barley remember her she went on a "vacation" when I was only 4 never came back but I read it. The letter said: To my dearest Lizzie you need to pack a bag and some survival needs. If  3 of us have gone missing and never came back something is wrong. Go down to the basement there lies your grandfather's and your father's tools grab them.  Next go up the attic there will be a old chest with things you will need. If you can drive by the time you are reading this pack your car and go. But make sure no else has gone missing. All I thought of when I read that last line was oh no not my mother.  I could not help but cry my parents had divorced when I was 9. Rumor has it my father has evil blood which I am scared of the thought of that. Simply because my father was always nice to me however a very different man to everyone else.
