Do you see me now?

Who am I, you may ask? For most part of my life I was invisible. I had planned to keep being invisible until graduation, but fate had something completely different in store for me. Because of one dreadful day in the bookstore of Diagon Alley, things started to change drastically. I'm Raina Thomson, but I'm sure you've never heard of me before. This is my story. SB/OC.
