When I read these type of stories I put myself in 'Don't Think About It Too Much' mode. Then I pick a character and walk in his shoes. Of course this book is written for a younger audience. It's interesting how the writer, Stan Morris, develops the 'end-of-the-world-as-we-know-it' scenario into a survival lesson.  I must read the next book in the series as I have some unanswered questions ! ! !
