I enjoyed reading this book. It was told from 3 different point of views in which all go through lots of problems as the works falls apart.Empty shows the world go down little by little as oil starts to disappear. No one drive cars anymore. Oil based make-up is gone. Even food starts to go scarce because the cost of or is too much.Gwen stumbles upon a new technology in which ethanol is used. This is the start of a brand new world.My gripe is the live interest in this book. While I did like Tom, I really dislike his decisiveness. He just couldn't make up his mind. I also dislike how he came to Gwen.
