Angela is a boy living in a girl's body. She's transgendered and right in the middle of hir (hir is a combination of him and her) Junior year, she decides it's time to stop hiding who she really is and come out of the shadows. She has cut hir hair, bound hir breasts, and is going by the name Grady. This is a bold move for anyone, but for a high schooler, it is risky and causes all sorts of uproar.
Grady's family has its quirks, and hir mother and sister especially find it hard to accept Grady's change. The principle at school refuses to change hir name on transcripts because he believes she's just seeking attention and this will pass. Even hir best friend, Eve, abandons hir in hir time of need because she doesn't know how to deal with this change. Luckily, Grady becomes close with Sebastian, a rather geeky kid who doesn't seem to care what anyone else thinks. During this difficult period of adjustment, Sebastian becomes just the person Grady needs as a support and friend. Grady also develops a crush on Kita, a beautiful and extremely hip girl who is dating one of Grady's classmates. The whole novel isn't heavy, however. One of the most amusing parts of the novel is Grady's dad's love of Christmas and the lengths this family goes to to keep up their father's traditions of having a fully decorated (and gaudy) exterior, along with an interior that looks like something out of the Victorian era, on display for the neighborhood to view.
Through this story, we meet a strong willed person who knows hirself well enough to go against the grain in order to finally be happy with who she is, even if no one else understands. Although Grady doubts hir coming out at points because of other's reactions, she is also able to ask difficult questions and weighty subjects are discussed throughout the novel in an accessible and conversational manner. Sebastian and Grady bring up points about gender and if it is a stable characteristic that people should be judged on, if there is a gender scale where would people fall on it, and do people try too hard to act like the prototype of the gender they are labeled as? This is a well written story that is not too dramatic or heavy, but which deals with a subject that is not often addressed in young adult literature.
If you are interested in stories like this one or this issue I suggest reading Luna by Julie Anne Peters or Kate Bernstein's My Gender Workbook.
