The story was intriguing and I particularly felt the panic Malorie felt alongwith the confusion Boy and Girl felt. There were a few loose ends but it's an apocalyptic and post-apocalyptic story simultaneously, some plots may not be explained. The fear was constant. The unknown is always something we are scared of. The most emotional part was when Malorie felt she has to choose one of the kids to be the lookout. It's heartbreaking when the kids know what a near death experience is.
