Apparently I enjoy pre-apocalyptic stories more than post-apocalyptic stories. This was an enjoyable read, as the teen heroine struggles with family and anxiety as the end of the world approaches. The mystery of the vortexes and what, if anything, lies on the other side had me unsure just how the book would wrap up, and while I'm not entirely sure about the end, I don't find it entirely objectionable, either. Not sure if this will be my final pick, but it was the most enjoyable for me so far (with three of the six nominees read).
