The book is bad. Now, I may not be a literary expert. But I can cite a few things that were utter let down:
1. Character building. You can read the whole book and you won’t remember a single character
2. No story at all. From start till end you will look for a story. Sometimes you may imagine little hints. But there is none.
3. The book is repetitive and monotonous. It’s written same things over and over again.
4. Documentaries on space travel are far more interesting than this book.
5. I would say I was crestfallen almost all throughout the book
