It was of course Tolkien. I was probably six when I first saw the animated Hobbit. I loved it, and my uncle owned the book, though he had never read it, so he gave it to me, thinking it would be fun to watch me try to read it. So I tried. It was alittle advanced for me, but I muddled my way through with a dictionary close by. Really, I don't remember it being THAT difficult, but I do remember the dictionary. I quickly moved on to the Lord of the Rings, which caused some problems at school. Despite having a fairly advanced reading level for my age, I was not allowed to go into the "big kids" section, where the Lord of The Rings was of course (small town school/public library). My mother had to actually go to school board to get permission for me. It was a principle at this point, we could have bought the books.
Long and pointless anecdote aside, after all that it was finding The Blue Sword, and the rest of that series by Robin McKinley. She was a big influence on me, and is probably why most of my protagonists are women. That and the Chronicles of Prydain, which I recomement every child read before age 12.
