I had no idea what I was getting into when I started this book. This was not just heavy for the YA genre it is categorized in, but it was heavy period. Extremely well written and the diary style of the entries was absolutely invaluable (normally I find it annoying). Oddly enough, I feel like I am more prepared for some kind of catastrophe after this book. I also felt like I should start stock piling canned goods and water. I am interested in seeing where the other books head with the story. The small glimmer of hope in the end helped this book get one more star (I was feeling quite depressed while reading it). I definitely recommed it but, reader, be prepared.
