This story maked me think about what our world could be like if everything we knew was taken away and we had to start from scratch. Would humans disregard for the earth come back to bite us on the butt? Would our polluting of our planet be our complete dimise? How would we survive without all the technology we are accustomed to? How would we feed ourselves? Where would we live? These and many more are questions I asked myself as I read this book. It portrays humans as we are. Those of us who are willing and able to help our fellow man to the benefit of all and those of us who are willing to step on and hurt anyone that gets in the way of the things they want and the way they think things should be done. Definitely worth the read.
