This was the first book I've read by Frank Herbert. From what I've read about its background, it wasn't one of his best. It was written on commission in just a few weeks. I enjoyed many parts of it, but to be truthful, parts of it dragged along. Herbert paints a vivid and pretty believable picture of a human colony which lives underground and mimics the way of insect colonies. However, the conclusion was anticlimactic, almost as if added as an after thought.
