This World We Live In by Susan Beth Pfeffer

This review may contain spoilers of previous books in the series.
Summary:(from book jacket) It's been a year since a meteor collided with the moon, catastrophically altering the earth's climate. For Miranda Evans, life as she knew it no longer exists. Her friends and neighbors are dead, the landscape is frozen, and food is increasingly scarce. Miranda and her two brothers spend their days scavenging for food and household items, while their mother stays at home and desperately tries to hold on to the ordinary activities of their previous life. But they all know that nothing is truly normal in this surreal new world they live in. The struggle to survive intensifies when Miranda's father and stepmother arrive with a baby and three strangers in tow. One of the newcomers is Alex Morales, and as Miranda's complicated feelings for him turn to love, his plans for his future thwart their relationship. Then a devastating tornado hits the town of Howell, and Miranda makes a decision that will change their lives forever.
Review: Despite liking the first two books in the series I didn't really enjoy this one. I did like the plot and premise of this book a lot was interested in seeing how this final book would play out. There were a few plot twists and other things that made the book pretty exciting. The thing that really disappointed me in this book was the characters.
 First of all, I didn't find Miranda and Alex's relationship very believable. They had just met and had barely even spoken and then suddenly they are madly in love. Another thing was that Matt and Jonny were immature brats in this book. Jonny had a little more justification for his attitude but it was still kind of annoying. Miranda's character kind of went backwards form where she was at the end of the last book. She had changed so much over the course of that book but I didn't see it here. Both Miranda and Alex did and said things that were really stupid. And as for Miranda's big decision that she makes at the end of the novel  I don't think she should have done what she did.
  Despite my dissatifaction with the characters I really want there to be another book in the series. I know their probably isn't going to be but in some ways it was left way to open ednded for my taste. Anyway I guess i kind of had mixed feelings about this book.
