It was filthy. I don't know why that surprised me, since we scrub frantically to keep the soot manageable and there was no one at the library to do that. But there was something about the library being so cold, dark, and dirty that broke my heart. p.198Nothing like these books to make you want to take stock of the pantry and buy some more water. Because Life As Knew It and The Dead and the Gone were brutal. This World We Live In was less so and that was almost a relief. This was a good ending for this series though I didn't find it as affecting as the first or even the second one. The maturity that Miranda seemed to have gained in the first book is taken back a little as she still whines and fights a lot though not to the degree she did before. I started to question the ability of Miranda and Alex and her brothers to fall in love so quickly but then I realized that in extreme circumstances that this would have happened. Alex was never my favorite character but it was interesting to see him on the outside of the situation rather than close up like in The Dead and the Gone. He was still not my favorite character though the two of them are a good match. I was surprised at the new characters and I wanted to hit Matt for being foolish and a jackass. Miranda's mom seemed to be less of an influence and I think that was done on purpose. Overall it wasn't as powerful a book but it was an appropriate and right ending for the series.
