Book - George Orwell

I read my first novel at 18, George Orwell's 1984.  When I had finished it I thought, "That explains a lot!!!"  I had to read all his other works after the first to see if they all so insightful and I wasn't disappointed.  This book explains how he could write the way he did about what bothered him,  portraying George as an outsider in every aspect of his life, seeming always to be an observer and not a participant in it.
