This was one of the first alien invasion stories I've read. I love how Asimov delved into the aliens' society and thought processes. They were so much more superior than humans, hence the title.

One of the best syfy books I ever read 1000 stars if I could

During the first part of this novel, I realized just how much science Asimov was cramming into his science-fiction. The characters and plot took the time to detail the scientific basis of their world. That doesn’t happen much anymore, and I was really intrigued. Then I hit the 2nd part. The novel suddenly becomes bogged down in alien social networking and a seemingly endless string of dialogues about conforming to expectations. This new mode went on and on and on. I finally had to stop reading.
