This list is a far from complete list of some of my favorites - they are warriors, scholars, mothers, daughters; they can be wildly in love and impressively practical; they are a little too perfect and incredibly flawed. Most of them have happy endings, some of them don't. In an nutshell - these are girls who act like girls should and must.
1984 by George Orwell. I read it when I was in 8th grade I believe, and I was so disappointed that it wasn't a requirement in high school. Such a chilling novel, especially when you consider that some of Orwell's visions can be applied to today's world.
