Fantastic book. I wanted to read Isaac Asimov's Science Fiction Novels and it was the first novel in chronological order. Being the very first book I didn't expected much from it but Hehoshaphat this book was way ahead of my expectations.This book contains 18 chapter and all chapters are great but the last chapter was extremely thrilling and what a great chapter, my heart was beating so fast when I was reading the last chapter. Isaac Asimov is really a genius how greatly he blended mystery with science fiction in the book is truly amazing. Now I am going to read it's sequel "The Naked Sun" and am just thinking how much fun it would be. Read this book and youwon't regret it.
