hi! I was just wondering what books are available that you guys would suggest as a good "first book" or introduction to the topic of superstring theory. It's very interesting stuff to me, but unfortunately its also often over my head. thanks for any suggestions! _Andrew ps - I'd even be happy with "avoid the following books" responses.. at least that would prevent me from wasting time (and/or money) at the bookstore with something that probably won't help me.
