Pfeffer, Susan. Life as We Knew It. Harcourt Children, 2006.
At first I wondered if I'd make it through this book; if Miranda spent the entire book obsessing over prom, I knew I'd regret my decision to read it. Then, when it seemed like maybe she would realize that their situation was more dire than the lack of an internet connection, I worried that the end of the book would read, "And then my family died, and I ate them. And the cat." [Actually, I'm surprised that they didn't eat the cat; he survived to the end of the book.]
But the book ended on a hopeful note, so it was worth the read. I enjoyed Ashfall more than this book, since the main characters there are more concerned with their survival, and the catastrophic climate changes associated with a supervolcano seemed more realistic, but this was still a good book.
I just noticed on Amazon that this is book one in a four-book series. Probably I won't be reading the rest of them, although if I were at a library with patrons who read all things dystopia, I'd be sure to keep this series on the shelf.
