1 1 Introduction A few years ago, a friend asked me for young adult (YA) titles that represented sex positive experiences. She was preparing for her tween to begin asking ques- tions, and she was looking for books to share with her daughter. It occurred to me then that this wasn’t the easiest reader’s advisory answer, and I started wondering how sex was presented in recent titles. That was the beginning. As I started reading YA lit er a ture, I also began to consider how girls were con- structed in our culture—what did we believe about how girls experienced the world around them? This was partially because I was cognizant of the fact that the books I was reading were actually written by adults, and partially because my own pleasure reading including blogs like Jezebel, Feministing, and the Toast, and so I was steeped in stories of how our culture was reacting to women. While I began to read seriously feminist theory, I found my way to research on girlhood. It was here that I began to really wonder about repre sen ta tion of girls in YA lit er a ture and how that contributed to what we under- stood about girlhood. This led into research, but also reignited a passion I have, not only for YA lit er a ture, but for girls in YA lit er a ture. It is difficult to strike the right tone for this book because I am talking about two of my favorite things—girls and books for young adults, specifically titles that represent girls. I want it to be fun, because to me, reading is fun, and for the most part these are books I love because they represent girls in complex, messy ways. They are girls who are good, nice girls, and girls who are angry. Girls who do the right thing, and those who don’t. They hail from different backgrounds although they are still overwhelmingly white, middle class and heterosexual, which is a shame. And these books are thought provoking they might make you laugh, or cry, or rage, but they are fun too. But still . . . I want to take seriously what the representation in these titles tell us about what it means to be a girl and consider why it matters that YA literature contributes to girlhood.
