Any recommendations?

So, after reading Wither, I find that I'm curious about the Captured Heroine subgenre, mostly because I haven't read much along those lines. I'm not too concerned about genre -- I know that it's used some in romance novels, but like I said in my Wither review, really, I'd even put The Blue Sword in that category.

So let fly, if you've got any favorites!

(But nothing rape-y, please.)
