Smack me if you've already read them eight times, but have you tried Trickster's Choice and Trickster's Queen by Tamora Pierce?

I have!

(Incidentally, that kind of who-do-I-have-to-kill-to-get-out-of-here mercilessness was one of the things I liked about first-book Katniss. It's so unusual to see a non-villainous girl written caring about her own skin first.)

Fuck yes. I adored Katniss' ruthlessness and how she really didn't care about anything beyond her sister's life and then her own and then her mother's.
