How you rate this book probably depends on whether you think it is for children or adults. You can read plenty of other reviews pointing out all the plot implausibilities. As a dystopian vision for juveniles, believability should count for something, and on that score this book is third-rate. In that context, I'd give it two stars.I don't think the author was going for believability so much as setting up a platform to raise questions like "What price is too high to pay for social harmony?", etc. I guess this is one of those stories where the metaphor and the message are so much more important that the actual plot that the tale taken at face value is flat, ridiculous, and unentertaining. Sort of like The Little Prince or Johnathan Livingston Seagull. I don't really care for The Little Prince or Jonathan Livingston Seagull, so... two stars.
