Talk about a book series that is still haunting me. 
 I read all three of the "Last Survivor" books pretty quickly in a row. Book one we're with Miranda, book two we're with Alex, and in book three, we're back with Miranda. 
 I was very happy to go back to Miranda's family, because I enjoyed book 1 a pretty good amount better than book 2. For some reason Miranda's story connected with me more. 
 This World We Live In starts about a month after Miranda's last entry, and we basically pick up where we left off - the Moon is still too close to the Earth, there is still not enough food, not enough electricity, etc. I immediately fell back into the desperation and anxiety state of mind I had when reading the other books - I was checking my own electricity supply, considering what food I would have to eat if something like this happened, worried about the weather outside. 
 About halfway through This World We Live In, both book 1 and 2 start to mesh together. Alex appears in Miranda's life, along with other characters we had read about before. 
 I think the thing that makes this series so good is that Susan Beth Pfeffer is not afraid of disaster and doom. She does not try to make you feel warm and fuzzy, and none of the books had a perfect ending. Even at the end of this book there are horrible events that affect everyone - basically she is not a cop out, and it's something I really appreciate (even if it means my life is still affected by what I've read). 
 My favorite of the series is (still) number 1, but this series as a whole is a great addition to young adult literature.
