Shannon Hale's Enna Burning
The sequel to The Goose Girl departs from the world of already-existent fairy tales and focuses more on the previous protagonist's best friend, a girl who learns to control fire (handy and/or dangerous during a time of war). I have to say, Hale writes some badass heroines, and I like that there's romance but it's not the main plotline in either of these. Can't wait to read the next one (though I think that one's main character is a guy, but he's a likable guy from the previous two books, so that's okay). A.
