Just amazing! Its a superb science fiction story. Initially, it seemed to be a bit boring to me. But after the characters stepped beneath the earth, the phase of adventure started. Inside the earth, they encountered numerous primitive creatures and many more unexpected events passed through them. The author kept the suspense of the story from the time the characters entered inside the earth till the end. According to me its the best science fiction adventure novel.

excellent product quality and contents too.
