the overall tone and atmosphere of this book is darker than most of the others. tensions are high, most of the group members are crumbling one way or another, and even where there's camaraderie, cassie is very clear that it's just flashes of what it used to be, and that they're trying too hard to make it feel okay. there's little sense of hope for the future of the war

she is so full of guilt, and jake is depressed and angry. he's become a much more commanding and curt and abrupt leader, which is good for the war movement... but... rip jake. rip cassie.
