Maybe I'm not a reliable-enough reader, but I didn't particularly see a palindromic effect in the last part of the book. (Which to me still feels like the last third - to me, the book feels like the book has three sections: the setup, the survival, and the aftermath. I haven't read it in long enough to see if it's actually split that way in any sort of specific "Part 1, Part 2, Part 3" way.)
