I do think 'Hunger Games' sort of accomplishes that kind of ending, even while I am not generally a fan of 'Mockingjay' (i'm the 'disliked everything BUT the epilogue person)

I'm interested in what the Australian dystopias that influenced you were . . .even if I'm not likely to revisit that genre soon, would be good to have in my back pocket when i creep back to being fascinated by that canon.
