In the first book, she puts on a man’s clothes and finds that she can get the job she wants and act as assertive as she wants, much more so than when she dresses as a conventional girl.

 That’s what Jane’s cross dressing was to me, as the author, in the beginning. The discovery that it is easier for men than women to achieve in the ordinary world.

 But after Copy Boy, many readers came to me with questions about Jane’s sexuality, about her gender. They often asked, Is she gender fluid?

 Honestly, I didn’t know. I only knew that Jane experienced power and comfort in wearing pants that she’d never experienced in dresses (largely because the dresses lacked pockets, which Jane LOVES).

 In Tomboy, I’ve begun to look at that question more directly, asking nineteen year old Jane if she wishes she were a man rather than a woman. Or if she is attracted to women more than she is to men. She meets other characters in Tomboy who make that question more concrete.

 I’m not saying Jane’s got it all worked out in Tomboy, but that she is beginning to see she can be comfortable and assertive in dresses too (so long as there are pockets and no hosiery) and that she may find both men and women attractive.

 What Jane really wants is to be free to be herself, not to be forced into anyone else’s box. We’ll see as the trilogy continues with Flyboy how that desire for freedom works for her.

 So, if this fits with the definition of gender fluid, I suppose that’s what Jane is.
