Books in which girls disguise themselves as boys

I'm a big fan of this trope, because women in history were not allowed to do things that boys were allowed to do. I mean, even such a basic thing as go somewhere alone. A boy could, while a girl had to be escorted. So, I'm obsessed with girls not taking that as an answer, and doing what needs to be done. Sometimes, this included dressing up as a boy, because in the wise words of Amanda Bynes in She's the Man, "if you can't join 'em, beat 'em."

Also, just to point out, She's the Man is the modern movie adaptation of Shakespeare's Twelfth Night. If you haven't seen it, stop what you're doing, and watch it. Now. It's fantastic.

A Matter of Magic (#1 and 2) by Patricia C Wrede

"She's wearing a dress in the cover," I know, I know. And we all know how precisely accurate book covers always are, right? Set in Victorian England, Kim makes the mistake of trying to rob the wrong magician, and so begins her adventure.

A Spy in the House (#1 of 4) by YS Lee

Published Year: 2009
Genre: Historical Fiction
Subtitle: Great

Again with the dress on the cover! Well, she does switch between disguising herself as both men and women, so I can't really fault this one. Mary Quinn, a young orphan and thief in Victorian England, is saved from the gallows and plopped into a school for spies.

Defy (#1 of ?) by Sara B Larson

Ah, much better. A good knife on the cover definitely illustrates how these girls are fighting for what they want, even if it means dressing up like a boy. Set in a fantasy world, Alexa disguises herself as a boy in order to join the army and avoid the breeding houses, where exposing her secret could mean certain death. My review here.

Scarlet by AC Gaughen

And last, but not least, we have a knife and a pretty face. Now was that so hard? Scarlet, on the run from her past, disguises herself as a boy and joins up with Robin Hood's Merry Men in this adventurous retelling.
